Chemical Sensing: All-in-Fiber Chemical Sensing (Adv. Mater. 45/2012)
Photoconductive structures (PCS), embedded directly into the fiber cladding and extending its entire length, capture light emitted by a chemiluminescent material reacting with peroxide vapor flowing through the fiber core, as reported by Yoel Fink and co-workers on page 6005. The PCS directly transform this emissive signal into an electrical signal, thus facilitating a new all-in-fiber platform for remote and distributed photosensing. Image: courtesy of Yan Liang.
