A team of scientists are seeking to kick-start a wearable technology revolution by creating flexible fibres and adding acids from red wine.

Extracting tannic acid from red wine, coffee or black tea, led a team of scientists from the University of Manchester to develop much more durable and flexible wearable devices. The addition of tannins improved mechanical properties of materials such as cotton to develop wearable sensors for rehabilitation monitoring, drastically increasing the devices lifespan.

Team - Devices - Breath - Sensors - Hands

The team have developed wearable devices such as capacitive breath sensors and artificial hands for extreme conditions by improving the durability of flexible sensors. Previously, wearable technology has been subject to fail after repeated bending and folding which can interrupt the conductivity of such devices due to tiny micro cracks. Improving this could open the door to more long-lasting integrated technology.

Dr. Xuqing Liu who led the research team said: "We are using this method to develop new flexible, breathable, wearable devices. The main research objective of our group is to develop comfortable wearable devices for flexible human-machine interface.

Material - Suffers - Bonding - Fibers - Conductivity

"Traditional conductive material suffers from weak bonding to the fibers which can result in low conductivity. When red wine, or coffee, or black tea, is sprinkled on dress, it will be difficult to get rid of these stains. The main...
