The interest in dynamically tuning lens has attracted great attention to fabricate compact vision systems. Here, we discuss the fabrication and characterization of a simple, tunable, yet fully disposable, except imaging sensor, microfluidic-based optical device. The desired compact system is structured on a PDMS microfluidic. Tunable lens actuated by flow pressure (2 mm in diameter) is controlled...
A two-fingered micro hand has been available for use for years and allows dexterous manipulation of a single cell: grabbing, positioning, rotating and releasing. The end-effector of this micro hand consists of two glass needles; however, the glass tips must be finely adjusted and the micro hand must be calibrated prior to use. Because these initial procedures require highly skilled human operators...
A micro hand consisting of two rotational fingers is proposed. Each finger has 4 DOF: 3-DOF translation and 1-DOF rotation around the finger's axis. Two fingers grasp a small object and translate it in 3D space by moving themselves in the same direction. They can rotate the object by moving themselves back and forth in the opposite direction. Rotating the fingers around their own axes in the same...
A two-fingered micro hand has been developed for years and it allows dexterous manipulation of a single cell: grabbing, positioning, rotation and releasing. The end-effector of this micro hand consists of two glass needles. Before grabbing an object, the glass needles need to be approached to each other manually (initial setup). However, this operation requires high skill manual control, so that it...
