Created by the power of thought, the exoskeleton of the hand

Swiss engineers from the Federal Polytechnic School of Lausanne created a working prototype of the exoskeleton of the hand that can be controlled by the power of thought. The developers were able to do without implanting the electrodes under the skin, placing them on a special rubber helmet.

Impulses of the brain are transmitted from the helmet to the metal “tendons”, which are fixed on the wrists and fingers of the wearer with the help of Velcro fasteners, thereby causing the patient’s hand to move.

The exoskeleton itself is easy to use, installed in a few minutes, and still has the function of controlling the movement of the eyes, which was provided for completely immobilized people. It has already been tested for survivors of stroke and spinal injury patients, now the developers want to improve its work in such a way that it helps people fulfill their daily tasks.

In the course of research conducted by developers in the process of testing the exoskeleton, it turned out that when the thought is controlled by the apparatus of one hand, the brain regions responsible for the movement of the second arm are activated in the patient. Scientists plan to use this feature to improve development management and to complicate its design.

A hand scanner MolecuLight i: X will allow to see bacteria in an open wound

In Toronto, completed the first phase of clinical trials of the device called “MolecuLight i: X”. It is designed to make the world of microbes invisible to the naked eye clearly visible. After all, if the doctor knows exactly where the infection is, he can more effectively cope with it.

MolecuLight i: X is a hand-held non-invasive scanner that locates bacteria on the human body without contact with it. Everything happens in two stages. First, a picture of the wound is taken in high resolution under normal lighting, then similar, but with the light turned off and using ultraviolet illumination.

In the ultraviolet, the healthy skin looks pale green, and the bacterial colonies glow red. If two images are compared, the location and size of the population of harmful microorganisms can be determined with high accuracy. And apply the medicine point-by-point, without spending excess medicines and not affecting healthy tissues.

Clinical trials in the Toronto hospital showed that a competent doctor using the MolecuLight i: X scanner can accelerate the healing of a patient’s wounds by a factor of 9-10. After all, he not only sees the bacteria, but also tracks the healing process of the wound as a whole. It is expected that the technology will be approved for use in Canadian hospitals in the near future.
