Sustaining the power requirement for autonomous wireless and portable devices
Battery maintenance for a large-scale network consisting of hundreds or even thousands of sensor nodes may be difficult
Ambient power sources, as a replacement for batteries, come into consideration to minimize the maintenance and cost of operation
Energy harvester
FACULTY OF MECHANICAL ENGINEERING TEKNIKAL MALAYSIA MELAKA UNIVERSITY
Discovered in 1880 by Jacques and Pierre Curie during studies into the effect of pressure on the generation of electrical charge by crystals (such as quartz)
The converse piezoelectric effect is the change of strain or stress in a material due to an applied electric field

Output Voltage and Power delivered to the load resistance
Experimental vs Numerical Analysis
FACULTY OF MECHANICAL ENGINEERING TEKNIKAL MALAYSIA MELAKA UNIVERSITY
A model for energy harvesting of thepiezoelectric is presented. A maximum outputvoltage of 5.8 mV and output power of 48 pWwere obtained with load resistance of 400 kΩ.The experimental results are in reasonablygood agreement with the theory.
