Abstract
In this work we demonstrate the integration of a solid-state carbon nanotube strain gauge onto a soft, stretchable PDMS patch. We have designed, simulated and characterized the mechanical response of these devices. White-light interferometry is utilized to characterize the mechanical deformation suffered upon assembling the strain gauges onto the patches, and to determine key parameters such as the leverage factor η (1.25 nm/μm) which captures the strain transfer from the patch to the individual carbon nanotube strain gauge. Simulations show that η can be tuned by design for customizable sensitivity.
