Figure 3. Temperature Gauge Characteristics.

Figure 3

A) Graphical illustration of the structure of each of the three Wheatstone bridges each built using a 10 kΩ thermistor and three additional 10 kΩ thermistors. B) Resistance properties of the thermistors illustrating a near linear response over physiological temperature range of interest (20–40°C). C) Rate of change in resistance for the thermistors across the physiological temperature range. D) Theoretical temperature resolution of the temperature gauge across the physiological temperature range. E) Calibration of the temperature gauge.
