制作了一台微机电系统内燃机（MEMS IC发动机），演示了热能到机械能的转换。燃烧室的尺寸为5 mm × 3 mm × 1 mm（0.015cc），比表面积为3.07mm−1。活塞的往复运动可以通过燃烧压力和弹性弹簧的排斥力之间的力平衡来维持。在化学计量燃烧（当量比为1）下，将由氢和氧组成的预混合气体用作燃料。通过压力测量和火焰传播的直接观察来证实燃烧。火焰观测采用高速CMOS摄像机。最大燃烧压力为142.6kPa，排气量为9.5mm ~ 3，机械功率为29.1mW。这一实验证据为MEMS热机概念的实现提供了积极的前景。
A micro-electro-mechanical-system internal combustion engine (MEMS IC engine) is fabricated to demonstrate the energy conversion from heat to mechanical power. The dimensions and surface-to-volume ratio of combustion chamber are 5mm×3mm×1mm (0.015cc) and 3.07mm−1, respectively. The reciprocation motion of a piston can be sustained by the force balance between combustion pressure and the repulsion force of an elastic spring. A premixture gas composed of hydrogen and oxygen is used for fuel under stoichiometric combustion (equivalent ratio is 1). The combustion is confirmed by pressure measurement and the direct observation of flame propagation. A high-speed CMOS camera is adopted for the flame observation. A maximum combustion pressure of 142.6kPa, a displacement of 9.5mm3, and a mechanical power of 29.1mW were obtained for the MEMS IC engine. This experimental evidence provides a positive outlook for the materialization of the MEMS heat engine concept.
