Products that are only switched on and used when they are in motion can benefit from a simple sensor that detects slight movements and vibrations by means of a mobile micro sphere. The Sensolute MVS0409.02 omnidirectional Micro Vibration Sensor consists of a gold-plated ball that bridges two similarly plated contacts reducing the resistance between the two external connection pads from more than 30 MOhm to less than 100 Ohms. Packaged in a surface-mountable structure with dimensions of 2.85 x 2.45 x 1.7 mm, the fully passive sensor has an operating current of less than 0.2 µA and response threshold approximately 50 mg.
