Hand force sensing device

Abstract

The present invention is a hand force detection device, which includes a main body, a first gripping part, a second gripping part, a first plate, an elastic element, and a pressure sensing element. The main body is composed of the first shell and the second shell, and a first accommodating space is formed inside to accommodate related components. The first gripping part and the second gripping part are respectively disposed at different openings of the main body to accommodate different gripping methods of a user. When the user applies force, the hand force generated can be transmitted to the first plate through the gripping part, and the elastic element will undergo elastic deformation, thereby acting on the pressure sensing element.
