Title:
SENSOR AND METHOD FOR DETECTING HAPTIC SIGNAL
Document Type and Number:
WIPO Patent Application WO/2020/062635
Kind Code:
A1
Abstract:
Disclosed are a sensor and a method for detecting a haptic signal. The sensor comprises piezoelectrets, a ground layer, an amplifying circuit, and a controller. The piezoelectrets are provided on an outer surface of the ground layer. The piezoelectrets are connected to the controller by means of the amplifying circuit. The piezoelectrets are configured to convert an acquired haptic signal into an electric signal. The amplifying circuit is configured to convert the electric signal outputted by the piezoelectrets into a voltage signal. The controller is configured to output the type of the haptic signal according to the peak and time of the voltage signal.
