Electrochemical device for generating a time dependent electrical signal
A method and device to produce a potential between two electrodes immersed in an ion containing fluid on application of an external stimuli that produces a temporal shear flow of the fluid at the fluid/electrode interface. The external stimuli may be, for example, contact pressure, motion, vibration, electric and/or magnetic field, fluid flow, or a combination of more than one stimuli. The potential produced may be harvested for energy, or sensing the external stimuli. A method to provide family of energy generators to harvest energy from ambient energy sources, such as, motion, fluid flow, contact pressure, and vibrations. A method to provide self-powered sensors where the potential generated may be, for example, directly transmitted to a receiver for signal processing by wireless or wired communication. A energy generator and/or sensor is a also provided.
