Body Temperature Measurement

Learn how body temperature measurement and control is changing the medical industry through sensors.

Body Surface Temperature

External temperature measurement has advanced in technology with the addition of sensor technologies, increasing patient comfort, improving accuracy, and creating better tools for monitoring. Its data can be crucial to patients suffering from various conditions, from infections to hypothermia. The temperature measurement of the surface of the body can be accomplished using different sensor technologies. TE Connectivity (TE) manufactures NTC (negative thermal coefficient) thermistors, thermopiles, and digital temperature sensors to support the wide range of accuracy, packaging, and performance conditions amongst the different applications.

NTC Thermistor Sensors

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.  Certain designs are capable of withstanding 134°C autoclavable cycles.

 

Disposable designs are also manufactured for general purpose use, esophageal stethoscopes, Foley catheters, and skin surface temperature measurement.

Infrared Temperature Sensors - Thermopiles

Infrared (IR) temperature sensors enable accurate non-contact temperature measurement in medical applications. The most common applications for this type of temperature sensor is measuring ear temperature, forehead temperature, or skin temperature.  The sensing element is composed of multiple thermocouples on a silicon chip to measure an object's infrared energy.  TE packages and customizes thermopiles in various package sizes and with different wire lengths to accommodate customer needs. 

Digital Temperature Sensors

Learn how digital temperature sensors play a key role in our digital and connected world.

While not traditionally used for surface temperature measurement, digital temperature sensors are embedded into home healthcare and personal tracking devices.  These sensors provide accurate measurements of temperature with a digital output signal and small circuit board package.  For example, digital temperature sensors can be designed into medical devices to monitor the temperature of air in respiratory devices to create greater comfort for patients as air enters the airway.
