Demonstrator of a MEMS thermal actuator for improving the tracking accuracy of a hard disk drive head. This micro system was develop at the Delft University of Technology, in cooperation with DIMES (Delft Institute of Microsystems and Nanoelectronics), as part of the STW project 07213 ‘Advanced silicon micromachining for integrated 3D mechatronic microsystems’. Duration : [...]
Handheld, multi-axis camera stabilization device utilizing MEMS gyro sensors (U.S. Patent 7,642,741, additional patent pending) In the field of motion picture photography, camera stabilization devices are used to isolate the camera from the natural body movements of the operator, while providing fluid maneuverability across a set. The purpose of this project is to design, build and optimize [...]
The goal was to design, model and fabricate a precision MEMS-based clamp with a relatively large clamping force. The purpose of the clamp is to mechanically fix a six degrees of freedom (DOFs) MEMS-based sample manipulator once the sample has been positioned in all DOFs. The clamping force is generated by a rotational electrostatic comb-drive [...]
Optomechanical GHz Oscillator and Spectroscopy. Just like the spectral signature of materials originates from molecular vibrations, photonic devices have many spectral lines originating from their different mechanical modes. Our group has excited these modes using the radiation pressure produced by light circulating within the device (1, 2, 3) which oscillate regeneratively at controllable mechanical eigen-frequencies [...]
This video shows the first comb-drive actuator experiment in Suranaree University of Technology, Thailand performed on Tuesday 19th January 2010. This electrostatically driven comb-drive actuator had 19 fingers of rotor with 30 microns width of each finger. It was fabricated by synchrotron x-ray lithography technique at micromachining lab, the Synchrotron Light Research Institute, Thailand by [...]
The joint lecture about an introduction to MEMS, which was developed by Dr. Osamu Tabata at Kyoto University and Dr. Man Wong at Hong Kong University of Science and Technology (HKUST), has been also held in this year as a part of an educational program entitled “Micro Electro Mechanical System Creation” for the master course [...]
The JetXpert system (drop in flight analysis system) is now available with an add-on for nozzle plate visualization. This option has two cameras and two light sources. The face plate wetting module can save images and movies like the JetXpert system. Duration : 0:0:17
This is a demonstration of a dual brushed DC motor peristaltic pump control. This configuration can be used in microfluidics, fluidic mixing in industrial and other commercial settings. This compact controller is fully controlled via the USB. Duration : 0:5:7
University of Vermont’s Dr. Jane Hill’s Lab of the Engineering Department – animation on a section of research conducted by members of the lab. Animation by Katie Medrek. September 27, 2009. Duration : 0:0:35
This video shows droplet libraries which have been generated in capillary tubing using miniature droplet generators. The droplets are encapsulated in silicone oil. Each droplet is chemically isolated from the others and from the walls of the tubing. Trains of droplets in a ‘spool format’ can serve as miniature chemical libraries for high throughput screening.
