Abstract
A curvature radius measurer, an electronic device and a manufacturing method for the curvature radius measurer are provided. The curvature radius measurer is adhered to a panel. When the panel is pressed, the panel can be bent and deformed, and strain sensing resistors are deformed therewith, thus causing change of electrical characteristics of a curvature radius measurement circuit. The electrical property is only determined by the curvature radius of the panel, and the corresponding electric signal is obtained through the curvature radius measurement circuit, that is, the curvature radius of the panel at a pressed position can be accurately detected.
