- 요약As continuous wearable physiological monitoring systems become more ubiquitous in healthcare, there is an increasing need for power sources that can sustainably power wireless sensors and electronics for long durations. Wearable energy harvesting with thermoelectric devices (TEDs), in which body heat is converted to electrical energy through the Seebeck effect, presents a promising way to prolong wireless operation and address battery life concerns. To accomplish this, wearable energy harvesting devices will need to be made conformable and stretchable to operate on the human body and not impede comfort or movement. This requires advances in high-performance soft composite materials to keep power output high and not sacrifice bio-compatibility. In this dissertation, I introduce stretchable TEDs as a solution to both wearable health monitoring and soft robotic energy harvesting and thermoregulation needs. Liquid metal (LM) material architectures are introduced to replace traditionally rigid components such as coppers and ceramics. I focus this dissertation on (i) introducing TEDs that replace rigid components with LM composites, elastomers, and 3D printing, (ii) developing a novel approach to soft robotic actuation using liquid crystal elastomer (LCE) shape memory polymers combined with 3D printed TEDs, (iii) developing high power density TEDs and integrating them to power a PPG monitoring system, and (iv) exploring 2D MXene sheets in LM composites to effect the properties of thermal interface materials (TIM). (v) Lastly, I discuss future work on direct ink-writing of thermoelectric inks.
