Title: Infrared sensor systems and devices
Usefulness: Infrared sensor systems and devices
Summary: Used in a mechanical strain gauge and a microelectromechanical system (MEMS) based device, for sensing a change in strain induced by the presence of infrared radiation, that is utilized in medical, military, industrial and commercial applications. Can also be used for a thin-film transistor in which the photomechanical stretching strains the transistor channel and alters the transistor current.
Novelty: Strain sensor for sensing change in strain induced by infrared radiation, has strain-sensitive device including infrared sensing material, where absorption of infrared radiation produces strain in strain- sensitive device

- *Abstract
-
The field of infrared detection is well established with many applications and associated design variations. IR sensors requiring high sensitivity typically need to be cooled to ultra low temperatures -- adding to their complexity and consequently making them more costly or unsuitable for ambient temperature applications.
To address this limitation, researchers at UC Berkeley, using a biomimetic approach, have developed a new type of IR detector that combines a modified strain gauge with an organic material for IR transduction. Infrared radiation incident on the organic material modulates a displacement of the material in order to detect the presence and intensity of IR radiation. This innovative design doesn't require cooling, and is sensitive to 9 and 3 ?m -- wavelengths that are emitted by mammals and forest fires, respectively.
