How scanning your finger could save your life

14.06.2005


Who would have thought taking a simple scan of your finger could save your life?



Unlikely on the face of it, perhaps, but a consortium including Cranfield Impact Centre and Nissan Technical Centre Europe, has developed a prototype bone density scanning system which could be used to improve driver and passenger restraint systems in cars.

The system would work by taking an ultrasound scan of your finger and using the data to estimate the bone strength of each passenger, in particular the chest area which is most vulnerable to seat belt injury during accidents.


This information would then enable the system to assess a person’s potential tolerance to injury and adjust the force of their seatbelt accordingly so it ‘gives’ a little once the brakes are applied and the car begins to decelerate.

It will also adjust the firing of airbags. In cars with dual-stage airbags, for instance the system would be clever enough to decide whether or not to fire both stages.

Ultrasound was chosen because, unlike x-rays, it uses no ionising radiation. This not only makes it a much safer option; its routine use in foetal scans makes it more likely to be readily accepted by the public.

Cranfield Impact Centre’s Technical Director, Roger Hardy, said: "The system could be built into dashboard consoles, the driver’s door or even, when miniaturised sufficiently, into the gear lever.

"It would need to be used each time the car’s ignition was switched on, before the driver was able to move off. In its simplest form, it could be a hole into which you place your finger; the instrument would be powered to lightly grip the finger, take the reading and then release. This would then feed into the restraint system, part of a processing unit in the car, in addition to what is routinely used to detect a go/no-go situation for firing airbags and controlling the seatbelt operating characteristics.

"A lot of the ground work has been done and we’re putting together our final report. We do, however, need to make further investigations before we look to commercialise the system," continued Roger. "We need to assess how it might be integrated into a car; what would be the power consequences on the battery, will it affect the engine management system, for instance – these are just some of the things needing consideration."

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
