The flexure hinge is a key component for designing compliant mechanisms that have been widely used in precision engineering which high positioning accuracy is demanded. This paper presents a systematic method for designing flexure hinges by using the topology optimization method. An optimization model is developed by equally considering the following three(More)
Dispensing and manipulation of small droplets is important in bioassays, chemical analysis and patterning of functional inks. So far, dispensing of small droplets has been achieved by squeezing the liquid out of a small orifice similar in size to the droplets. Here we report that instead of squeezing the liquid out, small droplets can also be dispensed(More)
In this study, we propose a practical method, in which a single grid image is utilized, to realize the calibration of an optical microscopic. This method mainly comprises four steps, including 1) Automatic detection of line features and point features from the grid image; 2) Correction of the lens Distortion utilizing the straightness of the line feature;(More)
