The temperature measurement of the surface of the body can be accomplished using body or skin temperature sensors. TE Connectivity manufactures NTC (negative thermal coefficient) thermistors, and digital temperature sensors to support the wide range of accuracy, packaging, and performance conditions amongst the different applications. NTC (negative thermal coefficient) thermistors are a common type of temperature sensor to measure surface temperature.  The sensor is a two-wire connection and uses the resistance properties of ceramic/metal composites to measure temperature.

For medical applications, packages are available with right angle or straight ¼” connectors to simplify installation.  Common applications for this type of temperature sensor include adult rectal, pediatric rectal, and skin probes. Disposable designs are also manufactured for general purpose use, esophageal stethoscopes, Foley catheters, and skin surface temperature measurement.
