Fluidic oscillations as energy source for flow sensors
Abstract
Fluidic oscillations can be used as an energy source for self-sufficient sensors. We designed, simulated and tested a fluidic oscillator based on the Coanda effect. It is able to work within media like air and water. Preliminary measurements show that our oscillator can harvest approximately 150 µW of power by coupling a piezoelectric chamber to one of ots channels. Future work will be focused on optimization of oscillators woth the help of an automation tool in order to offer an integrated self-sufficient wireless sensore node.
