Multi-phase EAP system and method for controlling such a system

Rick van Kessel (Inventor)

Research output: Patent


Method for an Energy Harvesting System using a plurality of EAP based sections (EAPN), including the plurality of EAP based sections, a power source/sink unit (PSS) and a controller. Each EAP based section includes an electronic charge/discharge unit (EN) and variable capacitor. The variable capacitor includes an elastically deformable body with an arrangement of stretchable synthetic material and electrodes functioning as the variable capacitor with a capacitance that varies as the deformable body stretches and relaxes. Each EAP based section is connected to the power source/sink unit by the respective electronic charge/discharge unit under control of the controller. The controller includes a processing unit, sensing circuitry and driving circuitry, with the processing unit being coupled to the sensing circuitry and the driver circuitry. The sensing circuitry is coupled to the variable capacitor of each EAP based section. The driving circuitry is coupled to the electronic charge/discharge unit. The method includes for each EAP based section: • receiving an state parameter signal/signals from the variable capacitor establishing a dedicated control signal based on the associated state parameter signal/signals received from the variable capacitor; • transmitting the dedicated control signal to the associated electronic charge/discharge unit.
