Spark Innovations Inc. is currently undertaking a project that develops new wearable temperature regulating devices (i.e., a patent-pending technology), which can effectively dissipate heat from target users to the surrounding areas. It aims to stimulate the physiology of the user, inducing weight loss all day long. The devices to be developed are required to be self-regulating, maintaining the skin temperature of the user at a constant level below that of the rest of the user's body. One of their applications is to serve as a thin-layer coating onto the inner side of apparel, facilitating efficient dissipation of generated body heat. Spark is targeting to integrate such devices in smart apparels for the promotion of body fitness. By incorporating cooling channels in the apparel, the body heat will effectively be transferred through the temperature regulating coating and subsequently be removed from the body. This smart apparel is expected to attract attention from and be welcomed by customers who are eager to shape their bodies. One key technological challenge to this technology is the needs to develop a new conformable and lightweight thermally conductive material system that can conform to the contour of body shape, and thereby perfect the contact between the temperature regulating device and the skin to facilitate heat dissipation. In this context, the over-arching goal of this research project is to develop a compliant film of highly thermally conductive polymer/hexagonal boron nitride (hBN) composite foams, and subsequently integrate them into a cold temperature regulation device to perfect its contact with the user's skin. The short-term objectives are: (i) design composite formulations and processing conditions to tailor the microstructure of polymer/hBN composite foams; (ii) investigate the effects of composite foams' microstructures on their conformability and effective thermal conductivity; (iii) develop the structure-to-property relationships of polymer composite foams in terms of their compliance and effective thermal conductivity; and (iv) evaluate the heat conducting performance of the flexible, thermally conductive film on hot bodies with different surface contours.

Spark Innovations Inc.目前正在进行一个开发新型可穿戴温度调节设备的项目（即一项正在申请专利的技术），该设备可以有效地将目标用户的热量散发到周围区域。它的目的是刺激使用者的生理机能，诱导一整天的减肥。需要开发的设备需要自我调节，将用户的皮肤温度保持在低于用户身体其他部位温度的恒定水平。它们的应用之一是作为服装内侧的薄层涂层，促进人体产生的热量的有效散发。Spark的目标是将这些设备集成到智能服装中，以促进身体健康。通过合并
