记录了实现外燃动态微型热机的进展。首先，描述了适合控制传入和传出微型热机的热传递的热开关的开发。其次，详细介绍了热开关与发动机的集成。热开关被证明是一种有效的手段，可以控制热量从连续热源传递到发动机以及从发动机传递到连续散热器。使用热开关可以使发动机循环速度高达 100 Hz，发动机效率高达 0.095%，功率输出高达 1.0 mW。测得发动机内部不可逆率为23%。
Progress toward the realization of an external combustion dynamic micro heat engine is documented. First, the development of a thermal switch suitable to control heat transfer to and from the micro heat engine is described. Second, the integration of a thermal switch with an engine is detailed. The thermal switch is shown to be an effective means to control heat transfer into the engine from a continuous heat source and out of the engine to a continuous heat sink. The use of the thermal switch is shown to enable engine cycle speeds up to 100 Hz, engine efficiencies up to 0.095% and power output up to 1.0 mW. The internal irreversibility of the engine is measured to be 23%.
