Abstract
- Summary Advances in stretchable conductors have been one of the main driving forces behind the realization of wearable and epidermal electronics. However, retaining constant strain-property relationships under varying strain and strain rate remains a challenge. Here, we demonstrate a 3D structuring approach toward strain-accommodating, biocompliant conductors. In contrast to previous stretchable conductors, this method leads to polymeric materials with conductance that has zero dependence on (1) both tensile and compressive strain over an 80% strain range, and (2) strain rate from 2.5%/min to 2,560%/min. Their Young's moduli can be controllably tuned between 10 and 300 kPa. In addition, these conductors are ultra-lightweight and can be molded into virtually any shape and size. Their properties mimic the dynamic and softness of biological systems, rendering this a versatile platform for designing electronic materials that can potentially form intimate interfaces with humans.
