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 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 vibrationcollected 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 temperaturesensor. Nitrogen compound aluminum vibration collector. Displacement vibration energy collected by Shaft Position Sensor 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. Both programs are considered to be the original innovation, especially in the industrial sector after promising a program that is promising . This reminds me of the importance of interdisciplinary . In China, it was also studied low -power sensors,self-powered sensors, Crank Position Sensors nodes. However, people were asked to engage in computer power plus local power control , engage people to lower the voltage electronics , modify the circuit , who were asked to engage in strategic research needs of people who engage inmaterial made ​​of certain materials CMOS process modifications . All of these ideas are good , that is, as stated above do not form a Camshaft Position Sensorsolutions and experimentally demonstrate its feasibility. Our old gave me a feeling of floating on top , or nowhere near enough analogy something more , something to talk about on paper more. Recently, I reviewed adomestic article about software fault tolerance. His talk about the real software fault-tolerant technology, but between the methods to study various software fault-tolerant scheduling algorithm . You did not study a software fault-tolerant way , how do you choose , scheduling it ? On paper can only be empty talk
