Biodegradable Microsensors for Food Monitoring

Microsensors are used in many different applications such as the detection of poisonous gases. They are also integrated into miniaturized transmitter/receiver systems such as RFID chips. Since the sensors often contain precious metals that are harmful to both the environment and human health, they are not suitable for medical applications involving direct contact with the human body, or for inclusion in food products. There is a need for microsensors made from non-toxic materials that are also biodegradable.
