Researchers at The University of Manchester have developed graphene sensors embedded into RFIDs, which may have the potential to revolutionize the Internet of Things (IoT). The team layered graphene-oxide over graphene to create a flexible heterostructures that function as humidity sensors for remote sensing with the ability to connect to any wireless network.

The novel aspect of this development is that such sensors can be printed layer-by-layer for scalable mass production at very low costs. The device also requires no battery source as it harvests power from the receiver.

Sensors with a RFID enabler are at the center of the much talked-about IoT. The tea, explains that this new development can provide various applications such as battery-free smart wireless monitoring for manufacturing processes that are sensitive to moisture, food safety, healthcare and nuclear waste. The developed technique has the potential to simplify how the information is gathered through its wireless system, nor is it is limited to a particular wireless network and has the ability to be compatible with networks including WiFi and 5G.
