Description
This work reports the development and test of an energy harvester (few centimetres sized) designed to power the miliwatts required in submersible monitoring systems, that uses water movements as energy source. The device was fabricated with moulded materials (epoxy resin and silicone), using additive manufacturing for mould fabrication. The device was characterized with movements from 0.1 Hz to 0.4 Hz, and the maximum power of 7 Mw WAS measured in emulated environment. Power was used to charge a lithium rechargeable battery (for levelling energy sourcing and demanding) and tested to power turbidity sensors
