如今，在日本，通过丰富的电力实现的舒适的生活方式和环境正受到夏季“凉爽商务”、冬季“温暖商务”的能源消耗削减政策的质疑。这些政策的原因之一是现有间接为人体制冷或供暖的空调系统的能源消耗效率较差。一些研究一直在调查人体直接降温和升温的影响。然而，大多数提出的解决方案集中于直接头部或颈部冷却，使用冰来冷却水循环系统，这样的使用过程中的温度无法精确控制，也无法适应用户和环境条件。最近，日本的一个研究团队开发了一种采用珀尔帖元件的便携式系统，可以冷却和温暖颈部。虽然在夏季炎热环境下降温被证明对生理和心理状态都有积极影响，但在寒冷气候下只能证实颈部变暖，而对脚和手没有影响。为了开发有效的直接调节人体温度的节能技术，减少身体寒冷带来的不适，我们提出并开发了一种基于珀耳帖元件的腕戴式可直接加热人体的可穿戴设备。第一项实验研究表明手腕变暖节律如何影响高温感觉。然后，我们验证了通过改变手腕被加热的位置是否可以改善包括四肢在内的身体的热感觉。
Today in Japan, comfortable lifestyle and environment realized by abundant electric power is being questioned by energy consumption reduction policies called “cool biz” in summer, and “warm biz” in winter. One reason of these policies is the bad energy consumption efficiency of current air-conditioning systems that cool or warm indirectly human body. Several researches have been investigating the effect of direct human body cooling and warming. However, most proposed solutions focus on direct head or neck cooling, using ice to cool a water circulating system, such temperature during use cannot be controlled accurately nor adapted to user and environment conditions. Recently, a Japanese research team developed a portable system using Peltier elements that can both cool and warm neck. Though cooling was demonstrated to affect positively both physiological and psychological state in summer heat environment, in cold climate it could be confirmed for only neck warming but not feet and hands. In our objective of developing effective energy saving technology for direct temperature-conditioning of human body, and in order to reduce the discomfort caused by body chillness, we have proposed and developed a Peltier element based wrist-mounted wearable device that directly warms human body. A first experimental study showed how wrist warming rhythm affects hyperthermic sensation. Then, we verified whether the thermal sensation of the body, including the extremities, is improved by changing the position where the wrist is warmed.
