High temperature is one of the important reasons causing the fire in power system. Therefore, the early warning could be told by monitoring the temperature and effective measures could be taken. The corresponding accidents will be reduced. The traditional transformer winding temperature monitoring methods are electrical signal measurement and infrared measurement. Such electrical signal sensors...

An alternative method of rapid-cycle PCR for DNA amplification is demonstrated using electrolyte resistance for heating and temperature monitoring. The PCR amplification solution is electrically conductive and can be heated by passing an alternating current through the sample. The temperature of the solution is evaluated by monitoring its electrical resistance. Cooling is accomplished by forced...

Temperatures are effective indicators of the health of many machines such as the wind turbine gearboxes, bearings, engines, etc. This paper presents a novel wireless temperature sensor node powered by a thermal harvester for monitoring the status of gearboxes. A thermoelectric generator module (TEG) is optimized to harvest the electrical power from a heat source such as the gearbox undergoing s...

An inverse input–output method is proposed for long-term condition monitoring of civil infrastructures through the prediction error air temperature recorded at site a structure. It known that structural natural frequencies are affected by temperature. Hence, considers as input and output to train machine learning algorithm (MLA). To this end, after signal preprocessing using variational mode de...
