Aspects disclosed in the detailed description include a touch capacitance transduced energy harvesting system. The energy harvesting system includes a touch sensing electrode array and energy harvesting circuitry coupled to the touch sensing electrode array. When a movable conductive object (e.g., a human finger) moves toward or away from the touch sensing electrode array, capacitance of the touch sensing electrode array increases and decreases accordingly, thus transducing a direct current (DC) current in the touch sensing electrode array. As such, the energy harvesting circuitry can be configured to harvest electric energy from the DC current to generate and store a DC voltage. By harvesting the electric energy transduced from the kinetic energy of the movable conductive object, it is possible to power a low-power electronic device (e.g., a biosensor) with motions already used for interfacing with the low-power electronic device.
