Paper Title:
A New Method of Wireless Health Monitoring for SMA Composite Structure Based on Micro-Capacitance Measurement
  Abstract

In order to achieve the real-time monitoring internal state of composite specimen embedded shape memory alloy wires, a new wireless monitoring method in which PS021 is used to measure the capacitance change of composite structure is proposed. The micro-capacitance measuring principle of PS021 and the design of hardware and software of system are introduced in detail. The capacitance signal between some two wires of composite structure embedded SMA is measured by the PS021 module, and the measurement data are processed by C8051F330 micro-controller and wirelessly sent to PC by PTR4000. Compared the tested results with that of the high precision LCR meter, experimental results show that the relative error of system is less than 4.5%.
