  An ambient energy harvesting device was design and fabricated. It can harness
kinetic energy of rain droplets and low velocity wind flows. The energy
converted into electrical energy by using a single device. The technique used
by the device was based on the principles of electromagnetic induction and
cantilever. Readily available materials were characterized and used for the
fabrication of cantilever. Under the laboratory conditions, water droplets
having diameter 4mm and wind with speed 0.5m/s were used as the two distinct
sources. Without making any changes in the geometry or the materials used, the
device was able to convert kinetic energy from both the sources to provide
voltage in the range of 0.7-1VAC. The work was conceptualized to provide an
autonomous device which can harness energy from both the renewable energy
sources.
