a Schematic of the stretchable sensors with periodically wavy patterns. b SEM of the stretchable temperature sensor. c Changes in the sensor’s resistance value when the sensor strain is continuously stretched from 2.25 to 30%. d The relationship between resistance and temperature of a stretchable sensor with strains of 0%, 5%, and 10%.
