    摘要: A moisture sensor includes a pair of electrode plates separated by a moisture absorbent material that forms the dielectric of a capacitive sensor. As the absorbent dielectric material absorbs moisture, such as perspiration, the capacitance of the sensor changes reflecting a quantitative measure of perspiration absorbed. The sensor can be stabilized by capacitively coupling the dielectric material to the skin of the user to improve sensor stability and noise rejection. The sensor can include a capacitive sensing integrated circuit that measures the capacitance of the sensor in close proximity to the electrodes to limit the introduction of noise.

    摘要: An apparatus includes an electrical power source and a solid-state circuit located within a housing. The circuit is coupled to the electrical power source such that circuit is initially in an inactive state in which electrical current is prevented from flowing through the solid-state circuit, the inactive state corresponding to an OFF mode of the apparatus. The circuit further includes an active state in which electrical current is allowed to flow through the solid-state circuit, thereby turning the apparatus in an ON mode, the active state being triggered by a momentary voltage and remaining active after the momentary voltage is removed.
