![]() These alloys address limitations in previous devices, including an inability to stretch, inefficient heat transfer and a complex fabrication process. The filler material contained liquid metal alloys, which provide high electrical and thermal conductivity. To create these flexible devices, the researchers 3D printed composites with engineered functional and structural properties at each layer. The device also shows a 6.5 times increase in power density compared to previous stretchable thermoelectric generators. "We leverage additive manufacturing to fabricate stretchable electronics, increase their efficiency and enable their seamless integration into wearables while answering fundamental research questions."Įven after more than 15,000 stretching cycles at 30% strain, the researchers' prototype device remains fully functional, a highly desirable feature for wearable electronics and soft robotics. Because we want to use that energy for self-powered electronics, a higher power density is needed," said Mohammad Malakooti, a UW assistant professor of mechanical engineering. "It's a 100% gain if we harvest thermal energy that would otherwise be wasted to the surroundings. The team published these findings July 24 in Advanced Energy Materials. This device is soft and stretchable, yet sturdy and efficient-properties that can be challenging to combine. These initiatives and advantages compound to create an opportunity for the Emirates to lead the production of low-cost, low-carbon jet fuel from electricity while supporting the national energy and industrial sectors.University of Washington researchers have developed an innovative solution: the first-of-its kind flexible, wearable thermoelectric device that converts body heat to electricity. PtL mitigates many of these challenges and supports existing national initiatives. It is unlikely that hydrogen aircraft will be available in time to decarbonize the Emirates’ predominately long-haul network. The lack of biological resources makes it hard to scale traditional methods of SAF production. ![]() The aviation industry supports over 13% of the national GDP, and more than one in every ten people in the Emirates depends on aviation for a job.Įmissions from aviation, however, are projected to double by 2050 – even allowing for increased fuel efficiency – so the energy used to power the aircraft must be decarbonized. Aviation is uniquely important to the United Arab Emirates, with more aviation activity compared to the size of the economy than any other large country. The resulting SAF can be used to power existing and future aircraft sustainably. The sustainable crude produced by PtL can be refined in conventional facilities using the existing national infrastructure. Both dedicated and surplus electricity can be used for production, allowing PtL to create value from surplus power when the Emirates’ supply exceeds the demand. PtL involves the conversion of electricity into hydrogen, which is then combined with captured carbon to synthesize renewable hydrocarbons. The power-to-liquids (PtL) approach will allow the Emirates to use its considerable advantages – including intense sunshine and sustained winds – to decarbonize while avoiding some of the challenges of traditional sustainable aviation fuels (SAFs) pathways.
