Abstract (in Japanese) (See Japanese page) 
(in English) When the human body contacts with a metal with different electric potentials, electrical contact currents flow into the body, resulting in biological effects. The effects are frequency-dependent; stimulation of peripheral nerves at <100 kHz and thermal effects caused by the power absorption at >100 kHz. The ICNIRP guidelines and IEEE standard are the international standards for protecting human from adverse health effects. However, there is still a lack of knowledge about perception thresholds in the intermediate frequency band. This study focused on the thermal effects due to the contact current at the intermediate frequencies and estimated the threshold of thermal perception. First, we validated estimated temperature rise using the multiphysics computation by comparing with the measurement. Then, we estimated the thermal perception threshold at a fingertip by the temperature in figure estimated from the measurement
