Claim 11:
12. A method to harvest downhole energy, comprising:
receiving fluid from a wellbore by an inlet channel of an asymmetric fluidic oscillator;
oscillating the fluid by a feedback system of the asymmetric fluidic oscillator;
outputting the fluid oscillated by the feedback system to an outlet channel of the asymmetric fluidic oscillator, wherein the outlet channel comprises a first portion and a second portion positioned opposite the first portion, and wherein the first portion and the second portion are non-parallel to each other; and
generating, by at least one piezoelectric element disposed on at least one side of the outlet channel, an electric signal in response to variations in pressure of the oscillated fluid.
