Accelerometers combine low power with four full scales

The MIS2DU12 MEMS accelerometer from STMicroelectronics is a 2.0mm x 2.0mm x 0.74mm device designed for wearable and implantable medical applications, combining 20nA power-down current with sub-1µA active mode operation. It integrates motion processing for free-fall, wake-up, tap detection and 6D or 4D orientation, along with an anti-alias filter and 128-level FIFO to reduce host processor load and system power consumption. Supporting ±2g to ±16g full-scale ranges, 1.6Hz to 800Hz output data rates and operation from -40°C to +85°C, the sensor targets skin patches, glucose monitors and implantables such as cardiac monitors and pacemakers.
