Stretchable, Rehealable, Recyclable, and Reconfigurable Integrated Strain Sensor for Joint Motion and Respiration Monitoring

Figure 4

Characterization of the rehealed and recycled strain sensor. (a) Optical images of the original (top), rehealed (middle), and recycled (bottom) strain sensor stretched by 100%. (b) Stress-strain curves of the original, rehealed, and recycled strain sensors. (c) Relative resistance change of the original, rehealed, and recycled strain sensors versus applied uniaxial strain. Relative resistance change of the original (d), rehealed (e), and recycled (f) strain sensor under cyclic loading. The maximum strain is 40%. The insets exhibit magnified views of 10 cycles between cycle numbers 45 and 55. (g) Comparison of this work with previously reported stretchable strain sensors.
