Microscale energy sources are attracting much attention targeting at their application to mobile electronic devices, small-scale welfare equipments and autonomous robot such as micro air vehicle. Especially, conversion of chemical energy to electric energy inside those mobile devices has merits, because the energy density of chemical fuels is two orders of magnitude higher that that of high-performance secondary battery. In the present study, we aim at development of micro electret generator using micro engine and ceramic combustor.So far, we have fabricated micro catalytic combustor using high-precision ceramic tape casting technology, which is developed for LSI packaging technology. We successfully integrate nano-porous alumina layer in the ceramic microchannel as the catalytic layer. This combustor yields a combustion density of several 100 MW/m^-3. We have also developed a micro supersonic ejector, which introduces air into the combustor using the fuel pressure.

微型能源以其在移动的电子设备、小型福利设备和自主机器人如微型飞行器等方面的应用而备受关注。特别地，在这些移动的装置内将化学能转换成电能具有优点，因为化学燃料的能量密度比高性能二次电池的能量密度高两个数量级。本研究以微型发动机和陶瓷燃烧器为主要研究对象，采用大规模集成电路封装技术中的高精度陶瓷流延成型技术，研制了微型催化燃烧器。我们成功地将纳米多孔氧化铝层作为催化层集成在陶瓷微通道中。该燃烧室的燃烧密度为100 MW/m^-3。我们还开发了一种微型超声速引射器，它利用燃料压力将空气引入燃烧室。
