Abstract
The present invention disclose a smart coating comprising a substrate, optionally a first insulating layer, a plurality of first sensing units, a second insulating layer, a plurality of second sensing units and optionally a wear-resistant layer, wherein the plurality of first sensing units and the plurality of second sensing units have piezoelectric effect. The smart coating can provide real-time monitoring and feedback of the worn state of the surface of a part while eliminating the need to adhere a senor. Compared with the existing sensors and substrates bound by adhesion, the smart coating provided in the present application can avoid poor adhesion between the sensor and substrate. Furthermore, damaged positions can be located precisely so as to provide more and more accurate information regarding worn state of the part surface, which is in favor of monitoring and post-stage analysis on the worn state of the surface of the part.
