摘要： A battery for use in electronic devices and which is safely ingested into a body and a related method of making the battery. The battery includes an anode, a cathode and a quantum tunneling composite coating. The quantum tunneling composite coating covers at least a portion of at least one of the anode or the cathode and provides pressure sensitive conductive properties to the battery including a compressive stress threshold for conduction. The compressive stress threshold may be greater than a pre-determined applied stress in a digestive tract of the body in order to prevent harm if the battery is ingested. The battery may include a waterproof seal that extends between the quantum tunneling composite coating and a gasket separating the anode and cathode to inhibit the battery from short circuiting in a conductive fluid below the compressive stress threshold.
