Stingrays shock

STINGRAYS are helping Cov-entry University researchers make a breakthrough in sensor technology for use in the food industry and in medical testing.

The ocean stingray generates an electric charge using bodily proteins, making it ideal for the kind of sensor developed by Coventry researchers. The membrane produced for the biosensor from these proteins is just one-millionth of an inch thick. But the scientists, led by Ian Peterson, believe they have perfected a means of making it much more robust without sacrificing its sensitivity.
