Abstract: The application provides a pressure sensor and a wearable device. The pressure sensor includes a circuit board and a conducting elastic structure; the circuit board includes an electrode area which includes multiple electrode pairs set at intervals; the conducting elastic structure is set on one side of the circuit board and includes a first area; the first area includes a conducting part; when no pressure is applied to the conducting elastic structure, the conducting part is isolated from each electrode pair, so that each electrode pair is in an off state; when a pressure which is greater than a turn-on pressure threshold is applied to the conducting elastic structure, the conducting elastic structure deforms, so that the conducting part contacts with at least one electrode pair, and at least one electrode pair is turned on; wherein the turn-on pressure thresholds of different electrode pairs are different.

Abstract: The disclosure provides a flexible pressure switch. A flexible electrode region and a flexible non-electrode region are formed on a flexible printed circuit board at the bottom layer of the flexible pressure switch, two flexible electrodes separated from each other are arranged in the flexible electrode region, a conductive elastic composite body is adhered to and located on the flexible non-electrode region through an elastic adhesion layer, a pressure contact cavity region directly facing the flexible electrode region is formed on the conductive elastic composite body, and an upper surface of the inner wall of the pressure contact cavity region can contact the two flexible electrodes simultaneously or successively so as to switch on the circuit when being pressed. The flexible pressure switch is simple in fabrication process, low in cost, stable in performance and suitable for mass production.
