Abstract
An electronic coldpack and method of use are provided. The coldpack includes one or more thermoelectric components (e.g., thermocouples) that absorb heat at one surface and dissipate heat at another surface when energized (i.e., when electrical power is applied to the component). Multiple thermoelectric components may be aligned in a grid or other pattern, and sensors (e.g., temperature, optical, infrared) may be included in the coldpack and placed in proximity to some or all of the thermoelectric components. The sensors may monitor temperature output of the coldpack, monitor a temperature of an object to which the coldpack is applied (e.g., a body part), detect a skin condition (e.g., by skin color or temperature), or operate in some other way. In one mode of operation, the coldpack provides long-term uninterrupted cooling of the object. In another mode of operation, the coldpack is used to perform cryosurgery on a skin condition.
