How long can the displacement sensor life

We live in an age of advanced science and technology, should be carried out in various fields necessary for detection and analysis. Displacement Crank Shaft Sensor applications are increasingly widespread. That how to make it last longer displacement sensor? Both methods are based on the piezoelectric power generator, a micro-electromechanical systems (MEMS) cantilever converted into electrical energy to mechanical motion, and the motion of the cantilever can be driven in different ways. One is with a radioisotope, and another vibration collected with the environment. All self-powered communication nodes must maintain their memory state, periodically send its status. This requires 0.1 microwatts to 1 milliwatt of power.Cornell University researchers with a small amount of nickel -63 (Ni-63) to join its radioisotope neutrons in the nucleus made ​​of a piezoelectric generator. It can be a beta particle radiation harmless to maintain every 3 minutes 5mW RF pulses. Up to 100 years of its life.Netherlands an Imac nanoelectronics research center created a wireless, autonomous temperature sensor. Nitrogen compound aluminum vibration collector. Displacement vibration energy collected by Crankshaft Sensor Replacement generally require a specific vibration frequency of 1 micron. The sensor can measure the temperature every 15 seconds, and the data to the base station of more than 15 m. However, the sensor can not be packaged under atmospheric pressure, vacuum packaging in order to be up to 85 micro watts.
