A hydrogen sensor was won a Taiwanese research team a gold medal at a global exhibition in Switzerland.
The Semiconductor Transistor-Type Hydrogen Sensor, designed by engineers at the Department of Electrical Engineering from the National Cheng Kung University, won the award at the 38th International Exhibition of Inventions of Geneva.
Measuring one centimetre in diameter and weighing 0.6 grams, the portable application can operate at temperatures up to 300 degrees Celsius and requires just 50 milliwatts of power, Focus Taiwan reports.
According to the university, the device may be incorporated into design for car batteries, aeroplane fuel cells, spacecraft and hydrogen refuelling stations, which become more prevalent with the growing popularity of cars such as Honda Clairty that relies on such methods of refuelling.
It is also claimed that the sensor may be applied to communication products, micro electrical engineering and integrated circuits.
Other ideas showcased at the five-day event last month included a one-handed bottle opener and a electromagnetic plinth that can levitate various objects.
