    Abstract: A pressure detection module and an electronic device are provided. The pressure detection module is disposed between a support and an inner surface of a housing of the electronic device. The pressure detection module includes a first electrode, a second electrode, and a controller. The first electrode is fixed to an inner surface of a force input region of the housing, the second electrode is fixed to the support, and the second electrode is disposed opposite to the first electrode. The force input region of the housing is configured to drive the first electrode to move towards the second electrode based on a received external pressure. The controller is configured to determine a pressure detection result of the external pressure based on a capacitance change between the first electrode and the second electrode. The pressure detection module occupies small space in the electronic device, and is easy to mount.

    Abstract: A load sensor includes: a first base member; a second base member; a plurality of electrically-conductive elastic bodies formed so as to extend in a first direction on an opposing face of the first base member; a plurality of conductor wires extending in a second direction crossing the first direction between the first base member and the second base member; a dielectric body disposed between the electrically-conductive elastic body and the conductor wire; and a thread configured to sew and fasten the plurality of conductor wires to the first or second base member. A plurality of stitch rows, of the thread, in each of which stitches are arranged in the first direction are formed at a predetermined pitch in the second direction. Waving that supports a load does not occur, at least in a load detection range, in the target base member.

    Abstract: A capacitive flexible tactile sensor based on graded inclined micro-cylindrical structure, includes an upper electrode layer, a lower electrode layer and a dielectric layer between them. The dielectric layer is composed of an upper dielectric layer and a lower dielectric layer. The upper dielectric layer includes an upper dielectric layer base, upper dielectric layer long micro-cylinders and upper dielectric layer short micro-cylinders. The lower dielectric layer includes lower dielectric layer base, lower dielectric layer long micro-cylinder and lower dielectric layer short micro-cylinder. The upper dielectric layer long micro-cylinders and the lower dielectric layer long micro-cylinders are closely bonded, and there is a distance between the upper dielectric layer short micro-cylinder and the lower dielectric layer short micro-cylinder. The sensor structure of the present application is stable, overcomes the viscous effect.

    Abstract: A load sensor includes: an electrically-conductive elastic body; an electrically-conductive member having a linear shape and disposed so as to cross the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the electrically-conductive member. A width of the electrically-conductive elastic body in a longitudinal direction of the electrically-conductive member is changed such that a relationship between a load and a contact area between the electrically-conductive elastic body and the electrically-conductive member via the dielectric body becomes close to a linear relationship.
