March 3, 2025 – POLYN, a fabless semiconductor company supplying application-specific Neuromorphic Analog Signal Processing (NASP) technology and products, announces the release of the VibroSense Tire Monitoring Evaluation Kit for general availability.
VibroSense-TMS (Tire Monitoring Solution) is an innovative neuromorphic chip that processes tire vibration data to detect real-time tire-road friction changes. This game-changing technology extracts information essential for driving safety from within the tire using only microwatts of power. This allows friction change alerts to be instantly sent to the vehicle ADAS.
VibroSense TMS provides always-on, continuous friction monitoring, enabling vehicles to adapt braking, traction control, and autopilot systems more accurately to all driving conditions and increasing safety.
The evaluation kit includes a standard TPMS sensor node for data collection and a NASP model for friction monitoring. A SW SDK supports flexible model calibration for different tires. It operates with a live tire vibration signal, enabling the neural cores to be tested live under various road conditions.
The Data Acquisition Unit (DAU) is equipped with Infineon SP-49 sensor SoC and BLE for data transmission to a dedicated tablet (PAD) unit, which provides live visualization of the peak friction coefficient (PFC) estimation. The PAD GUI presents live PFC monitoring for two tires (e.g., front left and right).
POLYN’s evaluation kit helps innovative automotive, ADAS, and tire vendors start the integration and design processes for intelligent tire monitoring systems before product manufacturing.
“VibroSense transforms existing TPMS into real-time tire-road friction monitors, enabling next-generation tire intelligence and smooth integration with ADAS braking technology,” said Aleksandr Timofeev, POLYN’s CEO. “The task of transmitting vibration data from tires to the vehicle is challenging due to the high data volume. Our ultra-low-power neuromorphic processing solution solves the problem. VibroSense extracts the PFC values directly in the tire and communicates with the vehicle’s ADAS only if friction changes.”
“The intelligence in the VibroSense Tire Monitoring Solution Evaluation Kit is derived from the real-world collection of PFC labeled data, taken from various cars, tires, and surfaces, covering ten PFC levels of road friction, from 0.1 to 0.9. Different industries’ vendors related to automotive are invited to evaluate it,” added Timofeev.
POLYN’s NASP uniquely provides cloudless AI on IoT devices, supporting sustainability. POLYN enables Edge AI computing to be easily deployed across real-world IoT applications such as connected cars, industrial IoT, wearables, and consumer electronics.
