The concrete purpose is holding DNA, a cell, etc. softly. We formulated the technique of detecting the mechanical characteristic of the comb-drive actuator widely used as a micromachined actuator by electric admittance measurement. By using this, it is detectable that the tweezers arm which is carrying out resonance vibration contacted the cell in solution. Since attenuation of the amplitude can be grasped by admittance change, the monitoring of the strength of handling may be able to be carried out. The resonance characteristic can be observed though the viscosity resistance becomes large in a solution and the amplitude becomes small compared with air. Using this concept we evaluated mechanical properties of a fabricated comb-drive actuator and confirmed its practical usefulness for characterization of soft-handling tweezers","PeriodicalId":170356,"journal":{"name":"2006 International Conference on Microtechnologies in Medicine and Biology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125336510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atomic force microscopy measurements indicated that the deposition of lipid vesicles led to the formation of SLB membranes by vesicle fusion due to hydrophilic interactions with the exposed substrate.

We have evaluated the performance and measurement accuracy of the confocal micro-PIV system through the simple Poiseuille flow measurement.

The measurement results were compared with the theoretical solution of the Poiseuille flow in order to validate the measurement accuracy. The most dominant factor of measurement uncertainty is the effect of the Brownian motion of tracer particles. The effect of Brownian motion can be eliminated successfully by means of ensemble averaging method.
