| Outline of Final Research Achievements |
This research aimed at establishing methodology to make Micro Electro Mechanical Systems (MEMS), especially microactuators as well as transistor circuits, usable in aqueous environment. Special emphasis was put on integration with integrated circuit, referred as CMOS-MEMS. A foundry-made LSI chip was post-processed in open micro and nano fabrication platform in order to introduce new functionality to both MEMS and circuit itself. Several outcomes have been demonstrated, such as electroosmotic (EO) fluidic microactuator that demonstrated world’s lowest supply (5V), highest speed (137um/s, which is 7.4 times as fast as top value, to our best knowledge). As a direct application, liquid circulating LSI circuit cooling system for hostspot removal was demonstrated. Such microactuators are expected to provide future tiny MEMS agent that can autonomously go into hardly-accessible places for in-environment analyses. A couple of CMOS-MEMS devices for in-situ analyses have been developed.
