Wireless Device Senses Chemical Vapors

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad applications in military, commercial, environmental, and healthcare areas.The current design integrates nanotechnology and radio-frequency identification (RFID) capabilities into a small working prototype. An array of sensors uses carbon nanotubes and other nanomaterials to detect specific chemicals, while an RFID integrated circuit informs users about the presence and concentrations of those vapors at a safe distance wirelessly.Because it is based on programmable digital technology, the RFID component can provide greater security, reliability and range – and much smaller size – than earlier sensor designs based on non-programmable analog technology. The present GTRI prototype is 10 centimeters square, but further designs are expected to squeeze a multiple-sensor array and an RFID chip into a one-millimeter-square device printable on paper or on flexible, durable substrates such as liquid crystal polymer.SourceAlso: Learn about Extended-Range Passive RFID and Sensor Tags.

Telematics: An Industry Game-Changer

Telematics is the transmission of machine data to a remote consumer. If that remote consumer is an electronic device rather than a human, the process is called machine-to-machine (M2M) communications. The emerging M2M revolution is based on innovations in hardware and software that are converging to form a whole new way of transacting business.

Boosting Energy Efficiency of Multi-Hop Wireless Networks

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.
