MEMS accelerometers suit wearable, hearable designs

BOSCH BMA530 and BMA580 accelerometers are tiny sensors for space-constrained applications such as wearables or hearables. Devices provide improved performance in a small package – delivering easy implementation without detailed application knowledge. Built-in features enable the BMA530 to track motion activities with a step counter that is especially suitable for wearables. At the same time, the BMA580 targets hearables with voice activity detection that features bone conduction. Compared to firm’s previous generation accelerometers, both devices have a 76 % smaller footprint (down from 0.95 mm to 0.55 mm.) in an Wafer Level Chip Scale Package (WLCSP), making them easy to place on a pcb and integrate into portable products.
