Abstract
The demand for energy-harvesting technology is steadily growing in the field of self-powered wireless sensor systems for use in pneumatic systems. The purpose of this research was to study an energy harvester excited by alternating air load in a pneumatic system. The harvester was designed to consist of a power chamber and a compressed chamber, and to the bottom of the power chamber a piezoelectric patch as been affixed. The harvester is excited by the changing pressure, which can be adjusted through changing volume, and the alternating air pressure energy can be harvested through the deformation of the piezoelectric patch. A test system was built and a prototype device was tested under various experimental conditions. The test results show that the energy generation performance of the harvester can be influenced by varying the volume compression parameters, with the output voltage increasing when the flow increases. The maximal output voltage and power are 24.7 V and 1.06 mW, respectively. An effective power of 0.28 mW was measured across the 200 kΩ resistor at a pressure of 200 kPa and a cycle time of 2.5 s with a flow of 150 L/min.

Summary
Energy-harvesting technology has attracted an enormous number of researchers to come up with promising solutions to develop real-time and endless energy supply for low-power electronics, such as wireless sensors and micro-electro-mechanical systems [1,2,3,4]. For their compact size and high-energy density, piezoelectric materials have been widely used in the research of feasible designs of devices [5,6,7,8]. Compressed air energy has attracted great attention due to its kinetic energy induced by piezoelectric materials [12,13,14,15]
