Valencell is a company active in high-performance biometric data sensor technology; in a joint announcement with STMicroelectronics the two companies have disclosed an accurate and scalable development kit for biometric wearables that includes ST's compact SensorTile turnkey multi-sensor module integrated with Valencell's Benchmark biometric sensor system.
Together, SensorTile and Benchmark comprise the most useful portfolio of sensors to support the most advanced wearable use cases, according to their designers.
The SensorTile is an IoT module (13.5 x 13.5 mm) that hosts an STM32L4 microcontroller, a Bluetooth Low Energy chipset, a wide spectrum of high-accuracy motion and environmental MEMS sensors (accelerometer, gyroscope, magnetometer, pressure, temperature sensor), and a digital MEMS microphone.
Integrating ST's SensorTile development kit with Valencell's Benchmark sensor technology simplifies the prototyping, evaluation, and development of innovative wearable and IoT solutions by delivering a complete Valencell PerformTek technology package, ready for immediate integration and delivery into wearable devices. The collaboration with ST expands on previous work that incorporated the company's STM32 MCUs and sensors into Valencell's Benchmark sensor system.
At just over 180 mm², STMicroelectronics' SensorTile can be used as a sensing and connectivity hub for developing firmware and shipping in products such as wearables, gaming accessories, and smart-home or IoT devices. It includes a Bluetooth LE transceiver including a miniature single-chip balun on-board, as well as a broad set of system interfaces. It can be simply plugged to a host board, and when powered it immediately starts streaming inertial, audio, and environmental data to ST's BlueMS smartphone app that can be downloaded free of charge from app stores.
