Sensing solutions for hearables
BMA400
Bosch Sensortec´s triaxial accelerometer BMA400 is the first real ultra-low power acceleration sensor. Accordingly, the BMA400 is especially suited for wearable devices, which need a long-lasting battery life. Furthermore, it is the ideal solution for smart home applications e.g. smart indoor climate systems and smart home security systems. By distinguishing between critical situations and false signals, the new acceleration sensor avoids false alarms.
BMA456
The BMA456 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces. The sensor is suitable for low-power and demanding consumer electronics applications. It detects wrist tilt, tap/double tap and enables plug ’n’ play step counting especially in wearable devices.
BMA550
The BMA550 sensor for hearables makes a big wave against unwanted sound waves. The innovative accelerometer works as body sound sensor for sensing bone conducted voice. Smart “voice enhancement” filters out distracting noises during phone calls and amplifies your own voice. This means that the person you are talking to can always understand you, even in noisy atmospheres. The BMA features 5-7x lower noise than standard accelerometers, low power consumption and high data rate up to 48 kHz for low latency.
BMA580
Stylish and minimalistic hearables offer little space for powerful components. The next-generation accelerometer with unique voice activity detection through bone conduction and advanced power mode features is the world’s smallest acceleration sensor (1.2 x 0.8 x 0.55 mm³). It is especially designed for compact devices such as hearables requiring the smallest components. BMA580 ensures that the microphone is turned on only if necessary to detect voice activity and save power.
BMI270
The low power BMI270 is an IMU optimized for wearables providing precise acceleration, angular rate measurement and intelligent on-chip motion-triggered interrupt features. The 6-axis sensor combines a 16-bit triaxial gyroscope and a 16-bit triaxial accelerometer featuring Bosch’s automotive-proven gyroscope technology. BMI270 includes several functionalities such as an integrated plug-and-play step counter/detector for wrist-worn devices. Moreover, the IMU is suitable for hearables, smart clothes, smart shoes, smart glasses and ankle bands.
BHI360
BHI360 is a highly integrated, ultra-low power, smart 6-axis IMU consisting of a 32-bit programmable microcontroller. In addition, it consists of an ultra-low power microprocessor, including pre-installed sensor fusion software and algorithms in a single package.
BMM350
BMM350 is a very small, high-performance, and low-current 16-bit 3-axis magnetometer. The digital sensor is ideally suited for a wide range of consumer applications such as AR/VR, head orientation, indoor navigation, magnetic compass, high-end gaming, and dead reckoning. The sensor is based on Bosch Sensortec’s proprietary TMR technology. The BMM350 magnetic sensor offers outstanding design flexibility, providing a single monolithic package solution.
BMP581
The barometric pressure sensor BMP581 is ideally suited for a wide range of altitude tracking applications like GPS modules, wearables, hearables, smart home and industrial products. This enables endless and new use cases such as fitness tracking where accurate altitude change is key. The low power and low noise 24-bit absolute barometric pressure sensor significantly improved its accuracy compared to previous generations at smallest size.
