Abstract : In the present paper, authors report on the fabrication and testing of an energy harvester using polymer blends of PVDF and PDMS from raindrops. The films were characterised using microscopy techniques for morphology and frictional properties. The piezo–ferro–triboelectric nature of the blends was analysed using electrostatic force microscopy (EFM). The infrared (IR) spectroscopy was used for phase enhancements in neat as well as blends of the polymer. Three different configurations of the devices were fabricated and tested with polymer blend metal contact yielding an output of 16 V and 15.4 nA for a piezo–tribo area of 2.25 cm2. The charging characteristics of the device yielded a power density of 0.177 µW/cm2, and the device was also tested for knock sensing applications. A prototype of tribo–ferro energy harvester installed on a modelled house rooftop yielded an output voltage of 0.795 V for 10 ml of water dropped from 8 cm.
