Skin is a tremendously complicated organ that performs a number of functions. Namely, to protect the body from outside influences and to convey information from the outside world. The latter is covered in today's episode.

Electronic skin is an engineered system that can receive information and then produce electronic potential, similar to the way our nerves work, and pass this signal to the brain. This has future potential applications in prostetic limbs to allow users to feel and respond using their prosthetic limb. 

Weichen Wang talks about his research into this area and gave a masterclass in the biology of the skin, nervous system and the difficulties with engineering electronic skin.
