Abstract Continuous powering of wearable electronics and personalized biomonitoring systems remains a great challenge. One promising solution is the use thermoelectric generators (TEGs) that convert body heat to electricity. These energy harvesters must conform curved surfaces minimize thermal barriers maintain efficiency while still exhibiting durability under large deformations. Here, highly efficient, stretchable made inorganic semiconductors printed multifunctional soft matter are...
Abstract As continuous wearable physiological monitoring systems become more ubiquitous in healthcare, there is an increasing need for power sources that can sustainably wireless sensors and electronics long durations. Wearable energy harvesting with thermoelectric generators (TEGs), which body heat converted to electrical energy, presents a promising way prolong operation address battery life concerns. In this work, high performance TEGs are introduced combine 3D printed elastomers liquid...
Flexible thermoelectric devices (TEDs) exhibit adaptability to curved surfaces, holding significant potential for small-scale power generation and thermal management. However, they often compromise stretchability, energy conversion, or robustness, thus limiting their applications. Here, the implementation of 3D soft architectures, multifunctional composites, self-healing liquid metal conductors, rigid semiconductors is introduced overcome these challenges. These TEDs are extremely...
Abstract Integrating liquid metal (LM) particles into compliant polymers presents an innovative approach for developing intelligent and adaptable systems in stretchable electronics, wearable devices, soft robotics, other emerging technologies. However, the inherent electrically insulative nature of these solid‐liquid composites, compounded by gallium oxide shell surrounding LM droplets, poses a significant challenge establishing conductive pathways, especially small droplet sizes ultrasoft...
Electrostatic patterning has improved the performance of devices incorporating electrospun fibers in a wide variety applications.
