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.

Microscale Energy来源在将其应用于移动电子设备，小规模福利设备和自动驾驶机器人（例如微型航空车辆）上吸引了很多关注。特别是，这些移动设备内化学能量到电能的转化具有优异性，因为化学燃料的能量密度比高性能次级电池的数量级高两个数量级。在本研究中，我们旨在使用微型发动机和陶瓷燃烧器开发微电部生成器。我们成功地整合了陶瓷微通道中的纳米氧化铝层作为催化层。该燃烧器产生的燃烧密度为几个100 mW/m^-3。我们还开发了一个微型超音速喷射器，该喷射器使用燃油压力将空气引入燃烧室。
