Adaptation of a Solid-State Marx Modulator for Electroactive Polymer

Electroactive polymers show promising characteristics, such as lightness, compactness, flexibility, and large displacements, making them a candidate for application in cardiac assist devices. This revives the need quasi-square wave voltage supply switching between 0 several kilovolts, that must be efficient, to limit heat dissipation, compact order implanted. The high- access resistance, associated with compliant electrodes, represents an additional difficulty. Here, solid-state Marx modulator is adapted cope electroactive polymer taking advantage of efficient energy transfer over sequential multistep charge/discharge process. To ensure efficiency, well needs implanted device, wireless magnetic field-based communication power system has been implemented. work demonstrates benefit this design through simulations experimental validation on device. At 7 kV, efficiency up 88% achieved complete cycle.
