Body temperature estimation system and method based on one-channel temperature sensor

A wearable temperature patch attached to a target person's skin and continuously estimating a body temperature, comprising:

• a base film;
• a skin temperature sensor installed on the base film, configured to be in contact with the target person's skin, and configured to measure a skin temperature at regular intervals;
• and
• a controller installed on the base film and configured to:
• receive the measured skin temperature from the skin temperature sensor, and
• estimate a current body temperature, based on an average body temperature measured at the regular intervals and the received skin temperature, by reflecting the average body temperature, the skin temperature, a skin temperature difference value (h) of the skin temperature, and a change amount (h′) of the skin temperature difference value,
• wherein the skin temperature difference value (h) is obtained by using skin temperatures measured at different times, and
• wherein the change amount (h′) of the skin temperature difference value is obtained by using skin temperature difference values (h) obtained based on different reference times.

A body temperature estimation system continuously estimating a body temperature of a target person, comprising:

• a wearable temperature patch configured to be attached to a skin of the target person and configured to continuously estimate the body temperature;
• and
• a management terminal configured to receive the estimated body temperature of the target person from the wearable temperature patch,
• wherein the wearable temperature patch includes:
• a base film;
• a skin temperature sensor installed on the base film, being in contact with the target person's skin, and configured to measure a skin temperature at regular intervals;
• and
• a controller installed on the base film configured to receive the measured skin temperature from the skin temperature sensor, and estimate a current body temperature, based on an average body temperature measured at the regular intervals and the received skin temperature, by reflecting the average body temperature, the skin temperature, a skin temperature difference value (h) of the skin temperature, and a change amount (h′) of the skin temperature difference value,
• wherein the skin temperature difference value (h) is obtained by using skin temperatures measured at different times, and
• wherein the change amount (h′) of the skin temperature difference value is obtained by using skin temperature difference values (h) obtained based on different reference times.

A body temperature estimation method comprising:

• receiving, by a processor of a management terminal, a skin temperature of a target person from a thermometer configured to be attached to a skin of the target person;
• and
• estimating, by the processor, a current body temperature, based on an average body temperature measured at the regular intervals and the skin temperature received from the thermometer, by reflecting the average body temperature, the skin temperature, a skin temperature difference value (h) of the skin temperature, and a change amount (h′) of the skin temperature difference value,
• wherein the skin temperature difference value (h) is obtained by using skin temperatures measured at different times, and
• wherein the change amount (h′) of the skin temperature difference value is obtained by using skin temperature difference values (h) obtained based on different reference times.
