These files contain data supporting the results found in figures reported in Jayamaha et. al., "Chiroptical Strain Sensors from Electrospun Cadmium Sulfide Quantum-Dot Fibers". In this work, we report, highly sensitive and reversible strain sensors from chiroptically active fibers embedded in elastomeric films. The chiroptical response on stretching is indicated quantitatively as reversible changes in magnitude, spectral position (wavelength), and sign in circular dichroism (CD) and linear dichroism (LD) signals and qualitatively as a prominent change in the birefringence features under cross-polarizers.
