Thermal shrinkage of thermoplastic films (a-c) and a stretchable temperature sensor packaged with the TEC (d). (a) Original status of thermal shrink films on the TECs and PDMS, (b) transient shrunk status by different time responses of thermal shrink films differentiated by different TECs after 7.5 minutes at 150 °C, (c) fully shrunk status of thermoplastic films on different TECs after 20 minutes at 140 °C and (d) the resistance change curve of the stretchable RTD packaged in the TEC and the transient thermal response of the sensors in the different packages (inset). The scale bars indicate 20 mm.
