Triboelectric-based cable sensors

Abstract:

Systems and methods for monitoring an environmental parameter. A system includes a sensing cable configured to produce a triboelectric signal along at least one conductor of the cable and an electrostatic voltmeter coupled to the sensing cable and configured to provide an output signal responsive to the triboelectric signal. A conversion module is configured to convert the output signal to one or more parameter values indicative of the environmental parameter, and an interface provides a usable representation of the parameter value. The environmental parameter monitored may exemplarily be temperature monitored by the sensing cable as a thermally expandable/contractible semi-rigid coaxial cable, or the monitored environmental parameter may exemplary be vibration, movement, or force monitored by the sensing cable as a deformable coaxial cable.
