Abstract
A touch activated control useful for incorporation into, e.g., a DON/DOFF sensor of a communications headset or a touch pad for a cell phone, includes a weakly conductive electrode and a sensor coupled to the electrode and operative to detect a change in parasitic capacitance caused by a change in the proximity of a body to the electrode. The electrode may include a covering made of a weakly conductive material. The weakly conductive property of the electrode enables the prevention of undesirable electrostatic discharge (ESD), user skin irritation and electrode corrosion caused by direct contact between the electrode and the user's skin and also exhibit's a substantially higher sensitivity than electrodes covered with an insulative material.
