TU Delft Optical Hydrogen Sensing & Thin Film Energy Materials

Today the work on an algorithm to surpress drift in optical hydrogen sensors was published in IEEE Sensors. Using the fact that a change in hydrogen concentration occurs in the vicinity of the sensor causes a different response to each wavelength, we designed an algorithm that can make optical hydrogen sensors more stable and reliable over time. Although the algortihm was illustrated using optical hydrogen sensors, its applicablity is not limited to those. Indeed, it can be used for any optical sensor. For this invention we applied for a patent. The publication can eb found here: Algorithm to Suppress Drift for Micromirror and Other Intensity-Modulated Hydrogen Sensors
