DescriptionThis thesis describes resistance-based soft sensors filled with liquid metal and a methodology for inductive coupling of electromechanical responses without wired connections. By compressing a tube filled with liquid metal, the cross-sectional area changed, and the sensor detected pressure based on the associated change in electrical resistance. The objective of this work is to understand the effects of material choice, geometrical layout, and relative position of coils on the sensitivity of the wireless sensor. A material testing machine compressed a polyvinylchloride (PVC) tube, a fluorosilicone tube, and a silicone tube that connected to a reader through an inductively coupled pair of coils. Relating measured phase to applied loads resulted in measured sensitivities of 270 millidegrees/N with PVC tubing, 78 millidegrees/N for fluorosilicone tubing, and 136 millidegrees/N for silicone tubing. In addition, when loading the PVC sensor at a rate of 1.44 mm/min and then 0.031 mm/min, the hysteresis changed by 85%. Strain sensing through inductive coupling has the potential to lead to future developments in haptics, smart gaskets, and epidermal electronics that will benefit from wireless connectivity.
