Q Could you please explain about key demos in display that uses MEMS and associated technologies in detail?
1. Wesu Smart Watch platform
- STEVAL-WESU1 FW provides a complete framework to build wearable applications, using inertial and environmental sensor drivers, battery profile measurements, and Bluetooth low energy for data communication
- The system embeds a low power ARM Cortex-M3 microcontroller unit (STM32L151VE), an iNEMO inertial module (LSM6DS3), a high performance magnetometer (LIS3MDL), a barometric pressure sensor (LPS25HB), a Bluetooth® low energy wireless network processor (BLUENRG-MS) and power management circuitry that allows fast charging and precise energy estimation (STNS01 and STC3115)

2. BlueMicrosystem
- BLUEMICROSYSTEM1 provides a complete middleware for STM32 to build applications using inertial (e.g. motion MEMS) and environmental (e.g. humidity, pressure, temperature) sensors, leveraging Bluetooth Low Energy for sensor data communication
- The package includes:
• osxMotionFX (INEMOEngine PRO under OPEN.MEMS license), which uses advanced algorithms to integrate outputs from multiple MEMS sensors in a “smart” way, independent of environmental conditions, to reach optimal performance
• osxMotionAR (iNEMOEngine PRO under OPEN.MEMS license) real-time activity-recognition algorithm
• osxMotionCP (iNEMOEngine PRO under OPEN.MEMS license) carry-position recognition algorithm
3. Voice over BLE
- BlueVoice + Android provides a complete example of STM32 application for voice streaming (acquired by digital MEMS microphones) over Bluetooth Low Energy to an Android device. The package is based on an improved version of OsxBlueVoice library which implements a vendor-specific profile, defining a service composed of an audio characteristic
- The BlueVoice+Android application supports three different audio compression algorithms: ADPCM, Opus and SBC. This package contains a firmware for the Peripheral unit and an .apk application for the Central unit. The software provides an example application for STM32 Nucleo platforms equipped with the X-NUCLEO-IDB04A1 expansion board featuring BlueNRG network module and the X-NUCLEO-CCA02M1 expansion board featuring one digital MEMS microphone
4. Lechal Smart Shoes and Insoles
- Lechal, has launched the world’s first haptic footwear that offers hands-free navigation. Their products contain ST microcontrollers, MEMS sensors, Bluetooth connectivity and power management devices
