Medical-grade motion sensor for implantable applications

STMicroelectronics has introduced the MIS2DH, a three-axis accelerometer specifically designed for medical applications. The MIS2DH can enable functions such as activity monitoring and posture sensing to be included in a range of medical applications.

There is a growing interest in the medical world in exploring how implantable devices could help treat chronic problems such as high blood pressure, epilepsy, and tremor-related conditions. For most of these applications, an embedded accelerometer capable of measuring the activity and posture of the patient is important to manage the stimulus delivered by the implantable device and therefore to improve the effectiveness of the treatment and the wellbeing of the patient.

Anton Hofmeister, general manager of ST’s Custom MEMS Division, said: "By combining our expertise in motion-sensing with a robust set of procedures for developing, manufacturing, and testing devices aimed at applications that meet the most stringent medical regulatory requirements, ST is contributing to important progress in this field by significantly lowering the cost and time-to-market barriers."

The MIS2DH measures 2 x 2 x 1mm, operates across a voltage range of 1.71 to 3.6V and features power consumption down to 2µA in low-power mode.
