Control Of Heat Capacity Of Moisture Sensor By Galvanic Arrays With Micro/Nano Gap Toward Accurate Detection Of Dew Condensation On Target

Accurate detection of dew condensation implies thermal control of sensor's surface to match the thermal behavior of target's one. Herein, thermal behavior of our moisture sensor was controlled by attaching heat sink to its backside while preserving thermal insulation. Temperature change of the sensor's surface was linearly related to the heat capacity of the heat sink and successfully relaxed against that of environmental target. A physical model based on Newton's law of cooling explains that the thermal insulation for the heat sink is another dominant factor to control the thermal behavior. Such combination enhanced the accurate detection of dew condensation.
