You walk into a plant and immediately your cell phone begins to buzz. But you don’t have a call. Instead, your phone just alerted you that the air is bad for your asthma or allergy. You reach for your inhaler or meds and the problem’s solved.
Gentag Inc. of Washington, D.C. has developed technology that can perform diagnostic functions from your cell phone anywhere, even if you don’t have phone service in the immediate area. The company recently received a patent for its product called the Method and Apparatus for Wide Area Surveillance of a Terrorist or Personal Threat. Handset makers who use this technology can program their devices to detect most chemicals, from pollen and carbon monoxide to the noxious gases dispersed by criminals or terrorists.
Gentag’s patent covers the use of this technology for personal wireless devices such as cell phones, PDAs, pagers or watches. The aim is to allow people with multiple chemical sensitivities to customize their personal device to recognize specific chemicals that cause allergies or are dangerous.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
