	1	Fully printed origami thermoelectric generators for energy-harvesting显示文摘Energy-harvesting from low-temperature environmental heat via thermoelectric generators(TEG)is a versatile and maintenancefree solution for large-scale waste heat recovery and supplying renewable energy to a growing number of devices in the Internet of Things(IoT)that require an independent wireless power supply.A prerequisite for market competitiveness,however,is the costeffective and scalable manufacturing of these TEGs.Our approach is to print the devices using printable thermoelectric polymers and composite materials.We present a mass-producible potentially low-cost fully screen printed flexible origami TEG.Through a unique two-step folding technique,we produce a mechanically stable 3D cuboidal device from a 2D layout printed on a thin flexible substrate using thermoelectric inks based on PEDOT nanowires and a TiS2:Hexylamine-complex material.We realize a device architecture with a high thermocouple density of 190 per cm2 by using the thin substrate as electrical insulation between the thermoelectric elements resulting in a high-power output of 47.8μWcm^(−2)from a 30 K temperature difference.The device properties are adjustable via the print layout,specifically,the thermal impedance of the TEGs can be tuned over several orders of magnitudes allowing thermal impedance matching to any given heat source.We demonstrate a wireless energy-harvesting application by powering an autonomous weather sensor comprising a Bluetooth module and a power management system.
