Robotic needle can be steered through tissue

By - August 27, 2015

A robot-assisted system developed at the University of Twente promises to make medical procedures that use needles more precise. The system allows flexible needles to be steered in real time to their target, which negates issues with tissue and organs deforming from the contact pressure or from any unforeseen obstacles that lie between the needle and its target.

Robot developed to perform ballast tank inspections on ships

By - November 24, 2014 2 Pictures
In order to maintain a consistent buoyancy as their cargo loads change, ocean-going ships pump seawater in and out of their ballast tanks. Needless to say, that salty water isn't exactly the least-corrosive liquid in the world. That's why crews of inspectors regularly have to go inside those steel tanks, to check for damage. Thanks to the German/Dutch RoboShip project, however, autonomous robots may soon be performing the task. Read More

MagnetoSperm could find use in drug delivery, or even baby-making

By - June 3, 2014
When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm. Read More

Researchers develop new microengine, but aren't sure how it works

By - March 22, 2014
If you’re going to do something like building a Porsche 911 that fits on the head of a pin, or make a microscopic medical pump, you need a microscopic engine. A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

Photoacoustic imaging promises breast cancer screening without ionizing radiation

By - May 10, 2012 2 Pictures
While breast cancer screening tests are accepted as safe – and we definitely wouldn’t want to scare anyone off from a potentially life-saving test – they do have some risks associated with them. The most obvious being the exposure to low doses of ionizing radiation, which in itself is a risk factor for breast cancer. X-ray mammography can also give false positive and negative results. In the quest for a safer, more accurate alternative, Dutch researchers have provided proof of concept that photoacoustic imaging can be used to detect and visualize breast tumors. Read More

Lab-on-a-chip counts and sorts sperm

By - October 31, 2011 2 Pictures
While just about everyone is familiar with home pregnancy testing kits, what many of us may not realize is that a (sort of) equivalent product exists for men - home sperm count kits. These kits, however, will simply tell users if their sperm count is above or below a standard value. While a yes or no answer like that might suffice for the pregnancy kits, a little more information would definitely help a man who suspects he might be infertile. Loes Segerink, a PhD student from The Netherlands' University of Twente, hopes to change that with this prototype lab-on-a-chip device. Segerink's chip counts exactly how many sperm are present in a sample of ejaculate, and can even differentiate between the good swimmers and the duds. Read More

ForceShoes enable extremely precise tracking of how their wearer walks

By - June 13, 2011 2 Pictures
There may not be many people interested in the precise measurement of all the forces and movements that are at play as someone walks, but for those few, a new tool has been developed to help them carry out their research - ForceShoes. Developed by researchers at the University of Twente's MIRA research institute in The Netherlands, these modest-looking sandals feature high-tech data-gathering electronics. Read More

Researchers demonstrate self-repairing chip

By - March 16, 2011 2 Pictures
As chips continue to get smaller, the technological possibilities just get larger. One of the trade-offs of miniaturization, however, is that smaller things are also often more fragile and less dependable. Anticipating a point at which chips will become too tiny to maintain their current level of resilience, a team of four companies and two universities in The Netherlands, Germany, and Finland have created what they say could be the solution – a chip that monitors its own performance, and redirects tasks as needed.
