Pre-brain surgery test protects language in some tumors

30/07/2020

A technique that maps a patient’s language centers before going into surgery works best when their brain tumor is not in those areas. The finding, published by Nagoya University researchers in the journal Scientific Reports, refines understanding of the test’s effectiveness and could help improve surgical planning.

Wearables: sensor patches as fitness trackers

29/07/2020

The Eurostars project XPatch is developing a flexible sensor system that can track biochemical information in real time. The international consortium is working on a new generation of diagnostic patches that monitor the sweat of high performance athletes for second-by-second medical information about their cardiovascular fitness.

New option for monitoring heart health

22/07/2020

An invention may turn one of the most widely used materials for biomedical applications into wearable devices to help monitor heart health. A team from Purdue University developed self-powered wearable triboelectric nanogenerators (TENGs) with polyvinyl alcohol (PVA)-based contact layers for monitoring cardiovascular health.

Human-like hands create safer human-robotics interactions

22/07/2020

In industrial settings, robots often are used for tasks that require repetitive grasping and manipulation of objects. The end of a robot where a human hand would be found is known as an end effector or gripper.

Wearable membrane for your health

02/07/2020

It is not only in summer that it can get hot during sports activities, because sport during winter also hasits pitfalls. Outside it is freezing cold, and insulating clothing is a must. To ensure that we don’t freeze in our wet clothes during our well-earned breaks, Empa researchers have developed an electro-osmotic membrane, which keeps clothing dry and thus warm.

Nerve stimulation: electric impulses relieve the pain

29/05/2020

The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear. It is of great importance for various body functions, including the perception of pain. Therefore, a lot of research has been focussing on how the vagus nerve can be stimulated gently with special electrodes.

AI: unlocking rhythms of 'deep sleep'

19/05/2020

Flinders University sleep researchers have used machine learning and artificial intelligence to develop a free online tool being used by sleep experts and researchers around the world to work out the role of the so-called K-complex, a prominent, brief up-down-up pattern of brain electro-encephalogram (EEG) electrical activity lasting around half a second during sleep.

Smartphone app detects cardiac arrhythmia

03/03/2020

Atrial fibrillation is one of the causes for a stroke and often appears without any previous indications. To reduce the risks and provide fast results, the application FibriCheck was invented. With the app it is possible to collect and measure data via smartphone camera.

Of exoskeletons and service robots – the future of rehabilitation

03/06/2019

For most people, enjoying a good quality of life means having the ability to move freely, safely and independently. Intensive and costly rehabilitation is needed if this is no longer an option after a stroke for example. We are introducing some projects that deliver innovative robotic solutions.
