Core Viewpoint - The research introduces the first n-type thermoelectric elastomers (TEE), which combine elasticity, stretchability, and thermoelectric conversion capabilities, potentially enhancing the performance of wearable devices' thermoelectric generators (TEG) in terms of skin conformity and energy conversion efficiency [3][5][7]. Group 1: Research Development - The study integrates uniform bulk-phase nanophase separation, thermally activated crosslinking, and targeted doping techniques into a single material system to create n-type thermoelectric elastomers [5]. - The developed TEE exhibits excellent rubber-like resilience under 150% strain, with a thermoelectric figure of merit (ZT value) comparable to flexible inorganic materials even under mechanical deformation [5][7]. Group 2: Application Potential - The research team successfully manufactured the first elastic thermoelectric generator (TEG) and demonstrated its application in harvesting human body heat, showcasing its potential to power wearable electronic devices and biosensors [5][7]. Group 3: Performance Optimization - Contrary to traditional views that insulating polymers dilute the active components in organic thermoelectric materials, the study found that carefully selecting elastic matrices and dopants can create a uniformly distributed, elastic encapsulated structure with highly n-type doped semiconductor polymer nanofiber networks, leading to synergistic optimization of electrical conductivity and thermal conductivity [7].
