Abstract
The novel approach proposed in this paper is called “All Mechanical Vibration Piezo-Electric Voltage Multiplier”; it allows the multiplication of the voltage produced by a piezoelectric transducer and it is based on a series of capacitors and mechanical switches (cantilever beams and stoppers) suitably connected. A suitable arrangement of switches, capacitors and piezoelectric transducers will result into the proposed mechanical voltage multiplier structure; no diodes are required and no control circuit is needed to allow the system to work. In this paper the working principle is introduced together with analytical models and numerical simulations. Experimental results are also reported to further confirm the validity of the proposed strategy: they have been obtained by using a macro-scale laboratory prototype.
