“…Furthermore, PDMS is employed to seal the gaps to prevent heat loss while protecting the device. 25,51 Additionally, the internal resistance ( R 0 ) of the F-TED increases by no more than 5% after 500 bending experiments with a radius of 12 mm. To ensure a stable temperature difference in PTM, copper foam strips are employed as a heatsink, effectively enhancing F-TED heat dissipation.…”
