Abstract

A keyboard module is described, comprising a plurality of keys (1) arranged in a housing and able to protrude from openings, in which each of the keys (1) comprises an elastic element (5) able to be pressed and deformed by a key cover (4) to operate a button switch (3) of a switch membrane (2). The elastic element (5) consists of a plurality of electrodes (511), (512), (521), and a plurality of intermediate layers (52), (53), elongated and deformed by an external force, when the external force is applied to the first intermediate layer (52) and to the second intermediate layer (53). Furthermore, an electrical generator is described comprising at least one elastic element (5) consisting of a plurality of electrodes (511), (512), (521), and a plurality of intermediate layers (52), (53), belonging to a keyboard module.
