We, as humans, have fairly advanced senses, but there is a great deal we can learn, copy and develop from nature. This programme looks at how we can draw on millions of years of evolution to enhance our own technology and methods of sensing the world around us. Some of the animal kingdom’s great ‘sensers’ include the common seal, whose whiskers can detect water turbulence over 30 seconds after it was generated; African elephants who are able to ‘hear’ sounds through their feet from potentially over 2 kilometres away and bats, whose ability to echolocate, has lead to the new design of a walking cane for the blind, and even a bike that can be ridden by a blind cyclist.
