The SensorTile is a tiny IoT (Internet of Things) module (13.5mm x 13.5mm) that packs on board a 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.
“Working with ST has allowed us to bring together the best of all sensors required to support the most advanced wearable use cases through our groundbreaking Benchmark sensor system,” said Dr. Steven LeBoeuf, president and co-founder of Valencell.
At just over 180mm2, STMicroelectronics’ SensorTile is currently the smallest turnkey sensor board of its type, and it is packed with a MEMS accelerometer, gyroscope, magnetometer, pressure sensor and a MEMS microphone. With the on-board low-power STM32L4 microcontroller, it 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.
Valencell’s PerformTek sensor systems provide accurate, robust and flexible technology, powering more biometric hearables and wearables. The technology gives wearable and hearable devices the ability to continuously and accurately measure blood flow signals, even during extreme physical activity or when the optical signals are weak. These signals can be translated into biometric data, including continuous heart rate, VO2 and VO2 max, resting heart rate, heart rate response, heart rate recovery, continuous energy expenditure (calorie burn), cardiac efficiency and heart rate variability assessments.
STMicroelectronics and Valencell will showcase the new integrated development kit at CES in the Valencell booth 44330 and in a private STMicroelectronics suite.
