Abstract
Systems, devices and methods for remotely interrogating sensor electronics are described. In one embodiment, a system for detecting and localizing chemical analytes is described. This system includes a plurality of chemosensor electronic devices for detecting the presence of chemical analytes. Each of these devices includes a chemosensor for sensing chemical analytes, a transponder, and an electronic circuit for activating the transponder based on an output of the chemosensor. These devices may have a cross-section area of less than 1 square micrometer. The system also includes an interrogation device for interrogating the plurality of devices and for receiving information on the detected chemical analytes from devices with activated transponders, and a processor for determining the locations of the devices with activated transponders. These locations may be forwarded to a third party.
