Abstract
An input module includes a substrate, at least two bio-keys and a control unit. The substrate has at least two bio-leads and switches. Each of the bio-keys has a key surface, at least one conductive elastic piece and a protrusion. The conductive elastic piece is electrically connected and conducted to the key surface and the bio-leads. The control unit has an input-signal generating element and a biological-signal generating element. The input-signal generating element is configured to generate a first input signal and a second input signal by using the protrusion to toggle the switch. The biological-signal generating element is configured to generate a bioelectric signal through the electrical conduction between the bio-key and the bio-lead. The present invention further provides an electronic device, in which the bioelectric signal is analyzed by an operational unit to generate a biological function index.
