Biodegradable microsensors
Monitoring the food supply chain
A team of researchers at Zurich ETH have developed tiny biocompatible, biodegradable sensors for food monitoring and temperature measurement. These highly flexible microsensors are six times thinner than human hair and are made of non-toxic materials. They dissolve in saline solution over the course of 67 days while continuing to function one day after being submersed in water. They could be used to check the cold chain remains unbroken during the transport of fish to Europe from Asia.

This innovation opens the way to a new generation of microsensors that could connect the physical world and the digital sphere. In this way food products could become part of a biological Internet of Things.
