  We report generation of electrical energy from nonlinear mechanical noises
available in the ambient environment using optimized piezo transduction
mechanisms. Obtaining energy from an ambient vibration has been attractive for
remotely installed standalone microsystems and devices. The mechanical noises
in the ambient environment can be converted to electrical energy by a piezo
strip based on the principle of piezoelectric effect. In this work, we have
designed and developed a standalone energy harvesting module based on piezo
transduction mechanisms. Using this designed module we harvested noise energy
and stored electrical energy in a capacitor. Using NI-PXI workstation with a
LabVIEW programming, the output voltage of the piezo strip and voltage of the
capacitor were measured and monitored. In this paper we discuss about the
design, development, implementation, performance and characteristics of the
energy harvesting module.
