Scientists with the University of the West of England have invented hi-tech urine powered socks capable of wirelessly transmitting a message and according to their inventors, they could be used to transmit their wearer’s location in the case of an emergency.
Relying entirely on human resources–urine for fuel and footsteps for pump–certainly has its advantage as the entire system is 100% self-sufficient. In order to pull off this feat, the socks are embedded with fresh urine activated miniaturized microbial fuel cells (MFC) – 24 to be exact. As the wearer walks around, the MFCs, which act as miniature batteries, are charged by the urine circulating around them.
Lead researcher Ioannis Ieropoulos, PhD, a professor of bio-energy and self-sustainable systems at the University of the West of England’s Bristol Robotics Laboratory, was quoted by The Telegraph as having said that after demonstrating the piss powered phone, he and his colleagues were curious to find whether or not they “could replicate this success in wearable technology.”
