| Popis: | The sensitivity of three different screen-printed highly stretchable liquid metal (Galinstan) sensors towards temperature and humidity as well as their electrical behavior under compressive load were studied. The sensors’ resistances show quasi linear dependence on changes in temperature without any hysteresis. Depending on the individual sensor design, changes in capacitance of up to 76% due to wetting of the sensor area with tap water have been observed. When applying compressive force, the capacitance values of all sensors show non-linear dependence and small hysteresis. In capacitive sensing mode, all sensors were especially sensitive to small forces ( |
