Algorithm to suppress drift for micro-mirror and other intensity modulated hydrogen sensors

Here, a method to suppress drift in intensity-modulated sensors is presented that preserves the advantages of such sensors including simplicity and low-cost components. This method is illustrated using metal hydride-based optical hydrogen sensors that can reliably, accurately, and quickly sense hydrogen across a large concentration range....

RGO-Based Memristive Sensor for Rapid Hydrogen Detection at Room-Temperature

In recent years, there has been a growing interest in investigating the potential of emerging memristor (MR) devices for gas sensing applications, particularly at room temperature. This article reports on a planar Au/reduced graphene oxide (rGO)/Au memristive hydrogen sensor, fabricated on a cost-effective cyclic olefin copolymer (COC)...
