N5 Sensors has developed a single-chip solution containing arrays of microsensors that can replace multiple power-hungry gas and VOC detection devices. Their technology integrates catalytic, electrochemical, and photoionization sensors onto a single GaN chip through nanophotocatalytic surface functionalization, allowing room temperature operation while reducing size, cost, calibration needs and power requirements compared to traditional sensors. Testing demonstrates the sensors can accurately detect various gases and VOCs with high sensitivity and selectivity.
