More Information
Summary:A downhole energy harvesting apparatus comprising a fluidic oscillator comprising: an inlet channel configured to receive fluid from a wellbore, a feedback system coupled to the inlet channel to oscillate the fluid, and an outlet channel coupled to the feedback system and configured to receive the oscillated fluid from the feedback system, and at least one piezoelectric element disposed on at least one side of the outlet channel and configured to generate an electric signal in response to variations in pressure of the oscillated fluid.
