The medical use of silk, like silk sutures or silk screws, has increased recently, taking advantage of the material’s biocompatibility, incredible strength, flexibility, and elasticity. Silkworms fed leaves coated in carbon nanotubes and graphene produce silk that is at least 50% stronger and can conduct electricity. Researchers are hoping that this new conductive silk will be used in sensors embedded in wearable electronics and medical implants.
