  • Publication number: 20190331540
    Abstract: The application provides a resistive pressure sensor and a wearable device. The resistive pressure sensor comprises a first conductive layer, an elastic insulating layer, and a second conductive layer. The elastic insulating layer is provided on the surface of the first conductive layer, and the elastic insulating layer comprises at least one through hole; the second conductive layer is provided on the surface of the elastic insulating layer, wherein the surface is far away from the first conductive layer. When no pressure is applied to the resistive pressure sensor, the first conductive layer is isolated from the second conductive layer, when a pressure which is greater than the pressure threshold is applied to the resistive pressure sensor, the first conductive layer and the second conductive layer contact with each other via the through hole.
