Anyone who has opened a carton of milk before its expiry date only to find that it smells off or tastes bitter has experienced the problem firsthand. For dairy processors, the same issue can play out across thousands of litres. Milk may pass routine quality checks, make it through production and still spoil before reaching the end of its expected shelf life.
CYBERTONGUE®, a biosensing platform, is designed to give dairy processors an earlier warning.
Developed by Canberra-based biotech startup PPB Technology, the compact food testing system allows processors to analyse milk on-site and receive results within minutes. Its first commercial application detects protease, an enzyme linked to spoilage, shorter shelf life and production losses across dairy products.
Dairy companies already test milk for fat, protein, bacteria, antibiotics and other indicators. Samples from individual farms may be sent to central laboratories, while tanker loads are tested again when they reach processing plants. These checks provide useful information, but they do not always show whether milk will remain stable in a UHT carton, meet a supermarket’s shelf-life requirements or produce the expected amount of cheese.
Even after heat treatment, protease can continue affecting milk. For processors making UHT milk, fresh milk or mature cheese, that creates a costly blind spot.
“Right now, dairy processors are working blind on this,” PPB Technology founder Stephen Trowell told Ventureport. “It’s becoming more of a problem as customers expect longer shelf lives and higher quality.”
CYBERTONGUE® uses engineered biosensing proteins that emit blue and green light. The balance between the two colours changes when the protein reacts with a target substance. The reader measures that shift and calculates how much of the target is present.
Trowell describes himself as a protein engineer at heart. He spent around three decades at CSIRO, Australia's national science and technology agency, and close to four decades in research before becoming a startup founder. The technology behind CYBERTONGUE® grew out of years of biological research, including earlier experiments involving wine aromas and explosives detection.
PPB initially developed its technology to measure plasmin, an enzyme derived from cows. After feedback from the dairy industry, the company shifted its focus to bacterial proteases, which were identified as a more pressing spoilage problem. The platform can make some existing tests faster, but PPB chose to focus first on a measurement previously unavailable to processors.
“Where we’ve chosen to lead is with a measurement nobody else can do at all,” he said. “The blue ocean, if you like.”
That focused entry point shapes PPB’s wider strategy. CYBERTONGUE® could eventually test for lactose, allergens, microbial toxins and other targets. Yet launching everything at once would stretch a six-person company too far. Protease gives it a clear route into dairy, where the financial value is easier to demonstrate.
A processor that detects high protease activity may redirect a batch of milk away from long-life products and use it for yoghurt, curd or another product where the enzyme causes less damage. PPB also says its tests can help trace problems in the milk supply and detect biofilms on processing equipment, allowing factories to take corrective cleaning measures.
Fresh milk presents another sizeable opportunity, with the global market estimated at around US$81 billion in 2026 and projected to grow at 6.83% annually through 2035. At that scale, even small gains in shelf-life consistency could prevent substantial losses. Supermarkets often require milk to have a minimum amount of shelf life remaining on delivery. Products that fall short may be rejected, discounted or discarded at the processor’s expense. While Australian processors typically aim for a shelf life of 19 to 21 days, they do not always achieve it. CYBERTONGUE® could help them reach that target more consistently.
Cheese producers face a related issue. Protease can create bitter flavours in hard cheeses and reduce production yield. Cheesemakers add another enzyme, chymosin, during production, often without knowing how much protease activity is already present in the milk. Better information could help them adjust the process and get more value from the same raw material.
PPB sells the reader as laboratory equipment, but its long-term business model centres on repeat testing. Customers buy the machine, then purchase a PPB reagent cartridge each time they run an assay. Future tests are intended to work on the same reader, making the system more useful as the catalogue expands.
CYBERTONGUE®’s compact design reflects PPB’s focus on practical onsite testing. The device is small enough to fit into two cupped hands and comes with a tablet running PPB’s software.
At the time of the interview, 13 to 15 systems had been installed with paying customers. PPB had made sales in 11 countries across five continents, with Europe as its largest market.
Trowell describes PPB as “born global”. While Australia and New Zealand have sophisticated dairy industries, Trowell thinks CYBERTONGUE® may offer even more value in regions where milk quality is less consistent, transport routes are longer or refrigeration is harder to maintain.
Trowell also believes PPB has a strong competitive moat, with the combination of manufacturing both the hardware and consumable reagents. Patents form one layer, but he does not consider legal protection sufficient on its own. A competitor would need expertise in protein engineering, reagent production, optical hardware, software and dairy processing.
Calibration adds another barrier. For each new box of reagents, PPB securely uploads the required calibration data to the customer’s machine. A third party could not simply manufacture a cartridge with the same dimensions and expect it to work correctly.
“We own the whole stack,” Trowell said, referring to everything from the sensing molecule to the hardware, software and cloud platform.
That said, he accepts that no technology is impossible to copy. His view is that PPB’s mix of scientific knowledge, integrated system and experience in dairy gives it enough of a head start to build a meaningful position before competitors catch up.
The technology could eventually reach beyond food. Trowell sees possible uses in environmental testing, veterinary care and medical diagnostics, including the analysis of blood, serum or saliva. PPB has already discussed potential applications with organisations outside the food industry.
For now, however, moving directly into clinical diagnostics would create more risk than opportunity. Medical products can require years of trials, extensive regulatory work and large development budgets. PPB would also need to build new sales channels and choose between many possible clinical uses without knowing which one would attract the strongest demand.
For these reasons, food testing offers PPB a clearer path. The regulatory barriers are generally lower, customers have immediate operational problems, and PPB has already built relationships in dairy. Once the platform has proved itself commercially, the company could enter other sectors through partnerships or licensing.
Trowell has held that view for years. The immediate goal is to build a successful food testing company rather than chase the prestige often attached to medical biotechnology.
The opportunity may also expand as food production becomes more complex. Dairy factories increasingly process oat, soy and other alternatives on equipment that also handles cow’s milk. This creates cross-contamination and allergen risks, offering another potential use for CYBERTONGUE®.
PPB still has plenty to prove. It must secure repeat reagent orders, convert early trials into wider deployments and expand its test catalogue without compromising accuracy. Scaling an integrated biotech hardware business across international markets will not be simple.
Still, its approach offers a useful lesson for other deep-tech startups. Instead of beginning with every possible application, PPB picked a specific problem that costs customers money today. It built a product around that pain point, then used the same technology as the foundation for a broader platform.
As Trowell put it, customers “need it fast, and they need it right.” CYBERTONGUE® is betting that food testing can deliver both.

A smartphone that moves, tracks and responds in real time—but is it real utility or just a marketing gimmick?

Smartphones today feel more familiar than new. Each year brings better performance and better cameras, but fewer real surprises. So when a company unveils something called a “Robot Phone”, it’s bound to get attention.
HONOR did exactly that at the Mobile World Congress (MWC) in Barcelona this year. While most smartphone brands are focused on software upgrades, HONOR is trying something different with hardware. Its Robot Phone is built to move and adjust on its own. The camera sits on a motorized system that can tilt, track motion and shift angles automatically. It almost looks like a small robotic head, following whatever is happening in front of it. It can pick up sound, recognize motion and stay visually aware of its surroundings. This result feels less like using a regular phone and more like interacting with something responsive.
So what makes HONOR’s Robot Phone different from the smartphones we already use? Here’s a closer look at its camera system, AI features and design, and whether it is truly something new or simply smart marketing.
At its core, the Robot Phone still works like a regular smartphone. What makes it different is the camera system. It has a 200MP camera that sits on a motorized arm with a three-axis gimbal, which extends when in use and folds back into the phone when not needed. The compact motor gives the camera physical movement, while motion control allows it to sense, track and follow a person or object in real time. That means it can keep a subject in frame without constant manual adjustment.
The camera also adds a more playful side to the experience. It can respond with simple gestures, such as nodding or shaking its head, and it can even move in sync with music.
This setup could be particularly useful for content creators. As CNET tech journalist and YouTuber Andrew Lanxon pointed out, it removes the need to carry a separate gimbal. Since the robotic camera module can easily fold into the body of the phone, it is easier to carry around and more convenient for filming or taking photos on the go.
The Robot Phone also has the practical advantage of a smartphone display. It gives users a bigger screen than a standalone camera for framing, monitoring and reviewing footage. Since it runs on Android, the process of recording, editing and sharing content is also more direct.
The most impressive part of the HONOR Robot Phone design is how it fits a moving camera system into the body of a smartphone without needing external attachments.
To make this possible, HONOR uses a custom micro motor that is 70% smaller than mainstream competitors. The company also says it is the industry’s smallest four-degrees-of-freedom (4DoF) gimbal system. To support the stable movement of the camera module, the internal structure uses high-strength materials such as steel and titanium alloy. These materials help the mechanism stay durable as it shifts and repositions over time.
Battery life is another obvious question. HONOR has not revealed the battery capacity of the Robot Phone itself, but it did showcase its Silicon-Carbon Blade Battery technology at MWC 2026. The company says this battery is designed to increase energy density while keeping devices slim, and that it could support capacities of 7,000 mAh and beyond in future foldable devices.
That is not specific to the Robot Phone, but it does hint at the kind of battery improvements that may be needed for smartphones with moving parts and more advanced camera systems.
The AI features in Honor’s Robot Phone are focused on how the device sees and responds to its surroundings in real time. At the most basic level, the phone can track what is happening in a scene and adjust itself without constant user input.
On the functional side, the system keeps subjects framed and in focus automatically. Its AI Object Tracking ensures subjects stay centred, while AI SpinShot enables controlled 90° and 180° rotations for smoother transitions, even when the phone is used one-handed. It can also detect motion and recognize sound, which lets it respond to activity as it happens instead of reacting frame by frame.
The AI becomes more noticeable in the way the device behaves. When activated, the camera module unfolds and the screen displays a pair of animated eyes that track the user’s face and gaze. Honor calls this “embodied AI”, meaning the assistant expresses itself through movement rather than only voice or text. The camera module can adjust its angle during video calls, which makes it feel a little more physically present.
According to Thomas Bai, AI product expert at Honor, the goal is to move beyond passive assistance. By combining sensing, movement and real-time processing, the device is designed to interact with its environment in a more continuous way. In practice, that could mean interpreting its surroundings and responding as situations change, such as when someone is moving through an unfamiliar space.
The Robot Phone has sparked curiosity, but there is still a lot we do not know. For one thing, it is still a prototype, with a release expected later this year. Early signs also suggest it may be expensive, partly because of rising memory chip costs. Some of its more playful features also feel uncertain. In demos, the phone can move along to music, but with only a handful of pre-set tracks, it is hard to tell whether that feature will be genuinely useful or remain more of a showcase moment.
Then there are the practical questions. A motorized camera system could make the phone heavier and more top-heavy, which may affect comfort during daily use. Running a motor alongside continuous AI tracking will also likely put pressure on battery life. These are not dealbreakers, but they are trade-offs that will matter outside of a demo.
Privacy is another concern that is hard to overlook. Some of the AI features rely on cloud processing, which means certain data is sent to external servers instead of being processed fully on the device. That is common in many AI systems today, but it feels more significant here because the phone is built to actively track movement and reposition its camera in real time. For some people, that level of autonomy may feel intrusive rather than helpful. It also raises bigger questions about what sensors are built into the device and how much data they collect during everyday use.
So, is the HONOR Robot Phone a real step forward, or just a clever idea packaged well?
The answer depends on who it is for.
For content creators, the appeal is obvious. Early indications suggest it could make video capture easier by reducing the need for extra gear. Honor’s collaboration with cinema camera company ARRI also suggests a serious push toward more cinematic smartphone footage.
For everyone else, the value is less clear. Outside of content creation, it is still hard to see how these features would translate into everyday use in a meaningful way.
For now, the Robot Phone sits somewhere between promise and experiment. Whether it turns into a genuinely useful new kind of smartphone or fades away as a novelty will only become clear once it moves beyond controlled demos and into real life.
