A miniature chemical actuator with a compliant expansion chamber, passive exhaust valve and electrowetting-based fuel injection

In recent years, an increasing amount of research projects contributed to the development of flapping-wing-micro-aerial-vehicles (FWMAV) that can fly and perform hovering flight in confined spaces. However, scaling laws have a negative influence on the aerodynamic efficiency and actuator efficiency. Consequently, FWMAVs suffer from very limited...

Dilating Pupil for Prosthetic Eyes Based on Electrowetting

The prosthetic eye is created to help people who have lost an eye. The eye itself can only improve the appearance but without any optic function. In order to optimize the appearance, a prosthetic eye with a pupil that can dilate and contract according to the light level, just like the natural eye, is desired. The primary goal of this work is to...

An Electrowetting Valve with Air Channel

In recent years, microfluidic systems are used in various fields. In important component is the valve. In a variety of valve principles, the electrowetting valve promises high reliability, good controllability, low voltage operation and high transmission speed characteristics. The micro-fabrication method to create a chip-level electrowetting...

E-MALDI: Optimized conditions during electrowetting-enhanced drop drying for MALDI-MS

We recently showed that electrowetting-enhanced sample preparation for MALDI-MS (eMALDI) can increase the intensity of the MALDI signal by 2-25 times compared to conventional drop drying by concentrating all the dried sample in a single spot rather than leaving behind a heterogeneous coffee stain pattern. Here, we demonstrate that the eMALDI...

Prosthetic eye with dilating pupil

Problem definition: The ocular prosthetic does not resemble the natural eyes enough, the pupil does not dilate and contract. To make the patients feel more complete the prosthesis should look as much as a natural eye as possible. Assignment: Improve the ocular prosthetic, by making it able for the pupil to dilate and contract, to let it resemble...

Innovative display technique for the building envelope: A research on electrowetting as smart glazing

This thesis is about electrowetting. Electrowetting is an advanced display technique that is going to take a part in the display competition against LCD screens and LED displays. Display techniques are becoming very important for the building envelope. The desire to have a responsive or adaptive building skin has never been as serious as the...
