POLYN Technology says it has begun delivering its VibroSense TMS engineering chip for assembly into tyre-mounted sensor nodes. The step allows potential customers to evaluate a system designed to estimate available tyre-road grip from vibration data, while a commercial chip and automotive qualification remain on the company’s roadmap.
POLYN Technology has begun supplying its VibroSense TMS engineering chip for assembly into AI-enabled tyre pressure monitoring sensor nodes. The company says tyre manufacturers, vehicle makers and chassis-system developers are among the potential customers able to evaluate the technology.
The distinction between chip and sensor node matters. Although POLYN’s announcement refers to engineering sensor nodes in its headline, the release says the chip is being delivered for assembly into those nodes. It does not name evaluation customers or confirm a production contract.
VibroSense TMS is designed to process vibration data at the tyre and estimate the peak friction coefficient of the road surface beneath it. That estimate could provide vehicle control systems with information about available grip. TNM’s earlier analysis examined the potential use of tyre-derived friction information in braking systems and the challenge of making it dependable across different tyres and conditions.
POLYN has also provided more detail about its previously reported braking claim. It says a vehicle fitted with VibroSense TMS stopped in 55.5 metres from 40 km/h on wet basalt, compared with 63.2 metres without the system. That is a reported reduction of about 12% under the stated test conditions. The release does not provide enough detail to establish whether the result would be repeated across other vehicles, tyres and surfaces.
The company says the technology requires calibration for each new tyre type, although the release uses the unclear phrase “tyre protector type”. How the system performs with different tread patterns, tyre wear and replacement fitments will be relevant to customer evaluations.
POLYN plans to tape out a commercially available chip in mid-2027, with automotive qualification to follow. For now, the announcement marks an evaluation stage rather than production readiness.
