Tittle:
Highly-sensitive hydrogen gas sensor working at room temperature
Summary:
Research team from a reputable Slovak university has developed innovative semiconductor hydrogen gas sensor with high sensitivity and short reaction time. The sensor works at room temperatures with significantly lower energy consumption compared to commonly used sensors, making it suitable for portable devices and for work even in dangerous explosive environment. The university seeks companies interested in financial agreement (technology purchase) or licensing agreement.
Description:
Hydrogen is considered to be one of the most significant and promising energy sources characteristic with high heat of combustion and low minimum ignition energy. Current industrial applications of this gas include metallurgy, glass industry, processing of semiconductor materials, oil extraction, chemical industry, but also biomedicine, environmental protection, indication of bacterial infections or the automotive industry. There are numerous types of commercially produced hydrogen detectors, however, their usability is limited by several factors including: large size of the detector, high purchase price, long reaction time, low sensitivity to lower gas concentrations, and most notably high energy consumption due to heating of the active area of the detector (typical operating temperature at the level of 200 - 400 °C). Providing a solution to eliminate these limitations is a subject of numerous research projects around the world, as the hydrogen gas sensor is a technology applicable in numerous fields of industry.

The presented technological solution of a semiconductor gas sensor does not exhibit any of the listed limitations. The sensor works at room temperature, has short reaction time and higher sensitivity to the presence of hydrogen. Due to its high sensitivity at room temperature, there is no need for heating of the active area, which decreases the energy consumption by more than 90% compared to the commonly used sensors. It is thus suitable for battery-powered portable devices and can be used in dangerous explosive environment (mining, metallurgy). Another advantage of the sensor is its compatibility with standardly used semiconductor technologies. Its topology allows easy on-chip integration with other electronic components. The sensor is based on a different physical principle as other common semiconductor detectors and is not limited by low selectivity (capability to differentiate hydrogen from other reduced gases).


Semiconductor gas detectors and particularly hydrogen sensors find application in various fields of industry including metallurgy, glass industry, processing of semiconductor materials, oil extraction, chemical industry, but also biomedicine, environmental protection, indication of bacterial infections or the automotive industry. The sensor has low energy consumption and works at room temperatures, which also enables operation in dangerous explosive environment (mining, metallurgy). The technological solution can be applied in any industrial field currently using similar technologies (semiconductor sensors), while delivering significant benefits in terms of energy consumption, sensitivity, production costs, and compatibility.

The university seeks companies interested in financial agreement (technology purchase) or licensing agreement (the university is looking for licensees).
