E-skin that can heal and stretch like the real thing

A group of international engineers have created an electronic skin that mimics the sensitivity, stretchability and self-healing properties of real skin. The film of skin can even detect strain, so could allow machines to 'feel' their surroundings when stretched or pressed. Combining a polymer, semiconducter material with an elasticated material, the engineers have created something tough and waterproof, that can self-heal fractures. But the future isn't here just yet - they more conductors and electric insulators need to be developed and integrated into the skin before it's safely wearable.
