Abstract
A bandage incorporates sensor arrays. The sensor arrays may measure temperature and are fixed to a person's temple in use, or other suitable body part. An estimate of core body temperature may be made using the arrays. The bandage may carry processing electronics and a transmitter. Processing may be done on the bandage or remotely from the bandage. Other physiological parameters may be measured depending on the type of sensor used.
Claims8
A device for the measurement of body temperature, comprising:
- a first array of temperature sensors arranged to determine a first temperature Tskin;
- and
- a second array of temperature sensors insulated from the first array, the second array of temperature sensors arranged to determine a second temperature Touter;
- and a data processor configured to estimate core body temperature (Tcore) using Tskin and Touter;
- wherein the first temperature is the highest temperature measured by the first temperature sensor array, and the second temperature corresponds to the sensor in closest physical proximity to the location where the highest temperature measured by the first temperature sensor array is, in operation, recorded.

A device for the measurement of body temperature, comprising:
- a first array of temperature sensors arranged to be placed in thermal contact with skin;
- a second array of temperature sensors insulated from the first array by a layer of material;
- an electronic circuit for converting output from the first array and the second array into digital representations of sensor output;
- an electronic circuit for wirelessly transmitting the digital representations of sensor output;
- a wireless receiver to receive the digital representations of sensor output;
- and
- a data processor configured to define digital representation of sensor output of the temperature sensor from the first array that measures the highest temperature as Tskin, and configured to define as Touter digital representation of sensor output of the temperature sensor from the second array which is in closest physical proximity to the temperature sensor from the first array that measures the highest temperature;
- and
- the data processor being configured to estimate the core body temperature (Tcore) using the following formula
- Tcore=Tskin+α(Tskin−Touter)
- using the two selected temperatures (Tskin and Touter), and a scaling factor α.
