Wearable thermoregulation device, system and method responsive to hot flashes

A wearable thermoregulation device configured to be worn on the body of a user, comprising:

• a band that is configured to be worn on the user's arm or wrist;
• a thermoelectric device carried by the band and that is configured to controllably heat and cool a control surface that is configured to contact the user's skin on one of the bottom or top of the user's arm or wrist;
• a power source carried by the band and that is configured to provide power to operate the thermoelectric device and either heat or cool the control surface;
• a controller carried by the band;
• a skin temperature sensor carried by the band at a location circumferentially spaced from the control surface of the thermoelectric device such that it is thermally isolated from the control surface of the thermoelectric device so that it is not influenced by heat or cold from the control surface, wherein the skin temperature sensor is configured to be in direct contact with the skin of the user and is configured to be used to sense skin temperature over time;
• a control surface temperature sensor carried by the band and that is configured to determine a temperature of the control surface, wherein the control surface temperature sensor is in communication with the controller;
• a wireless communications module carried by the band and that is configured to wirelessly send signals from the controller, and wirelessly receive signals, to control the thermoelectric device;
• wherein the skin temperature sensor is configured to be used by the controller to determine a skin temperature increase over time that indicates the onset of a hot-flash event;
• wherein in response to the determination of a hot-flash event the controller causes the thermoelectric device to cool the control surface;
• wherein the skin temperature sensor continues to monitor skin temperature without thermal influence by the control surface while the control surface is cooled;
• and
• wherein the controller is further configured to cause the thermoelectric device to stop cooling the control surface based at least in part on skin temperature as determined by the skin temperature sensor.
