In this study, the Karman Street was used to harvest the energy from the microchannel structure. The movement of the energy harvester is from the stable fluid flow through a semi-oval baffle which was made in the channel and the flow distribution triggers the Karman Street to yield vibration with constant frequency.
The channels were fabricated by multilayer structures. After using negative photoresist to fabricate the microchannel, a polydimethylsiloxane (PDMS) membrane was pasted on the surface of the microchannel and the vibrational potential was measured using the water flow through the polymer membrane to yield the variation of the potential.
The measured data was easily damaged when the micro-fluidic channel was full of water because the baffle was made by photoresist. Therefore, we fabricated an acrylic microchannel with one to two times bigger by a carving machine and the concept of micro-fluidic channel was feasible using the measurement of this study.
