Maximum temperature on surface of synthetic tissue sample for 100 mA contact current at nine different HF band frequencies as a function of contact current flow duration with a dry contact electrode. The above curves were developed by application of RF current via a 1 cm2 round disk electrode placed on a sample of synthetic tissue and measuring maximum surface temperature with a thermographic camera at the rate of 20 samples/s. Contact current was terminated just prior to the peak value of temperature shown for each curve
