A new method for temperature measurement in an infant incubator [using speed of sound]

In this study, we introduce a new measurement system to measure the temperature by using the speed of sound. This method based on the relationship between the speed of sound and temperature. Temperature was quantified by the speed of the sound. The distance between the receiver and the transmitter of ultrasound is positively associated with the resolution of the temperature. This method can provide a quick and precise monitoring for the temperature in an infant incubator.
