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.

微尺度能源因其在移动电子设备、小型福利设备和微型飞行器等自主机器人中的应用而备受关注。特别是，在这些移动设备中将化学能转换为电能具有优势，因为化学燃料的能量密度比高性能二次电池高两个数量级。在本研究中，我们针对微型发动机和陶瓷燃烧器的微型驻极体发生器的开发，目前已经采用针对大规模集成电路封装技术开发的高精度陶瓷流延技术制造了微型催化燃烧器。我们成功地将纳米多孔氧化铝层集成到陶瓷微通道中作为催化层。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音速喷射器，它利用燃料压力将空气引入燃烧室。
