ELECTRONIC SKIN REPLACES VOLUNTEER EXPERIMENTS

Abstract

Neutral electrodes (grounding plates used in electrosurgical operations) were tested with thermo cameras in volunteers experiments. These experiments are difficult to perform and expensive. A new test device swaroTEST with a measuring board "electronic skin" simulates the relevant electrical features of human skin to replace volunteer experiments. This device consists of a three dimensional resistor network representing the electric features of the skin and muscle tissue, and a temperature sensing array (one transistor for each cm²) to measure the resultant temperature increase after a standardized current load (700 mA hf current during 60 s, proposed in the relevant AAMI HF-18 standard). The comparison of test results with thermo camera images of volunteer experiments showed a sufficient coincidence, which proves the applicability of this test device to replace volunteer experiments.
