Energy storage and/or conversion device has energy storage device made of ferroelectric or piezoelectric material, with shape memory metal alloy or spring tensioned by electric motor

摘要

The device has an actuating element, e.g. a door handle, that can be operated mechanically and/or thermally and/or electrically and an energy converter and optimal energy storage device. The energy storage device is made of a ferroelectric or piezoelectric material. The energy storage device can have a shape memory metal alloy or spring tensioned by an electric motor.
