Description
Melisa E. Gülseren and colleagues build, in a 2026 study, an infrared sensor that listens to radio waves instead of light. Tiny vibrating radio-frequency devices, called RF MEMS, can be tuned to absorb specific infrared colors when paired with patterned surfaces. Earlier designs tracked shifts in vibration frequency. The new design watches changes in electrical impedance, the resistance a circuit presents, and ties them by formula to sensing strength.
The detector reached very high responsivity at room conditions, responding to infrared power down near a trillionth of a watt. It picked out a narrow color band around a chosen wavelength in the mid-infrared. Response time sat under a millisecond. Because a matching network can retune it, one chip could serve many sensing jobs. On-chip chemical fingerprinting for medicine and environment checks is the stated direction.
