BMA530

Stylish and minimalistic smartwatches offer little space for powerful components. The next-generation accelerometer with an advanced feature set is the world's smallest accelerometer (1.2 x 0.8 x 0.55 mm³). It is especially designed for compact devices such as wearables and smartphones requiring less sensor size.

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 conductedvoice. The smart function “voice enhancement” filters out distracting noises during phone calls and amplifies your own voice.
