MEMS and Sensors Enrich User Experience in all Application Segments

Sensors are now used widely, from typical mobile phones and tablets to an endless list of devices, limited only by what humans can imagine. From home to office, human to robot, sports monitoring to athlete performance improvement, machine vibration detection to factory preventive maintenance, asset tracking to inventory control, surgery to rehab. Where humans can dream, sensors can be put to use.

Applications

A recent startup company’s inspiring news release announced that they are using gyroscope technology to reduce hand tremors in patients suffering with Parkinson’s disease.  Patients can wear a glove embedded with the gyroscope which monitors shaking and a motor is used to counterbalance the motion.  With steady hands, patients can stay independent longer and live with dignity.  Although the device is still being tested, advancements in reduction of sensor size, power consumption, noise, and cost allow for life changing possibilities.
