Abstract

A device () for converting a movement of a user into a voltage comprises a neck cord (), a piezoelectric sensor () and a printed circuit board (). The neck cord is coupled to the piezoelectric sensor and provides in use a pulling force that acts on the piezoelectric sensor in a first direction. The printed circuit board is electrically and mechanically coupled to the piezoelectric sensor. The weight of the printed circuit board cause in use a gravity force to act on the piezoelectric sensor in a second direction, which differs from the first direction such that the movement of the user () wearing the neck cord causes a change in the shape of the piezoelectric sensor which in response thereto generates the voltage. The voltage may be used as a supply source for an electrical component () mounted on the PCB, or may be used as a wake-up signal for an electrical component such as a processor () or an accelerometer.
