Using Metal Oxide Nanocolumns to Detect Fire

A team of Korean scientists have announced a selection of metal oxide sensors that can detect these gases faster than commercially available detectors; and potentially be used in a new line of ultra-sensitive fire detectors. Quite simply, the more sensitive the alarm is, the faster it can alert us..

Graphene in bolometers: sensitivity and scale

By integrating a graphene amplifier with a pyroelectric (LiNbO3) substrate scientists at the Cambridge Graphene Centre constructed a bolometer with a TCR of 900% K-1. This was achieved by fabricating a floating metallic structure that concentrates the pyroelectric charge on the top-gate capacitor..
