Abstract

This paper presents a novel approach to energy scavenging for a micro-electro-mechanical system (MEMS) device to convert the energy stored in pressurized gas into electrical power. The proposed design uses input pressure to move a piston and magnet through a set of coils while pulling on another mass through non-linear springs to open and close the input air valve. The model demonstrates that the design is capable of staying in motion with continual input pressure (up to at least a time stamp of 1 second), and that an average power output of 9.47 μW over 5 ms can be achieved. We suggest that further research be done to optimize the design parameters and that the optimized design be used to the test the system.
