From: A nanoforest-based humidity sensor for respiration monitoring

a–c Recovery curves for the sensor at different heating temperatures; the insets show infrared images of the microheater at different voltages. (d) Recovery times of the humidity sensor when the microheater is operating at different voltages. e Response time curves of the thermistor when the microheater is operational. f Infrared temperature measurement curve and self-detection temperature measurement curve of the microheater
