MICRO ELECTRO-MECHANICAL STRAIN DISPLACEMENT SENSOR AND USAGE MONITORING SYSTEM
A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.
