The project at Loughborough University aims to overcome limitations associated with current motion detection techniques that can be hamstrung with limited range, restricted mobility (due to bulky, rigid components), high-cost, and the need of replacing/recharging batteries.
The lack of infrastructure and trained professionals in rehabilitation is a worldwide issue that has been intensified by the ongoing pandemic, which has reduced access to healthcare.
Telemedicine and telerehabilitation try to address these issues by providing remote and affordable access to healthcare using telecommunication devices, such as smartphones and tablets.
This shift requires new methods that can gather inexpensive and accurate data on physiological parameters – such as heart rate, blood pressure, body temperature, and hormone levels – and body movements in real-life settings.
Now, Dr Ishara Dharmasena, of Loughborough’s School of Mechanical, Electrical and Manufacturing Engineering (MEME), has been appointed a Research Fellow by the Royal Academy of Engineering and awarded funding of £500,000 to develop a new technology that overcomes these challenges.
Dr Dharmasena will look to make electronically active clothing from textile yarns that capture energy from body movements and generate electricity using Triboelectric Nanogenerators (TENGs).
Absorbing the movement from the body, these smart textiles will power electronic components and act as self-powered functional sensors that are able to accurately sense the movements of targeted body parts.
This textile system will then wirelessly communicate the data to a mobile device – resulting in a highly efficient, durable, light-weight, wearable, low-cost rehabilitation monitoring product.
Dr Dharmasena hopes to have two fully-functioning smart textile demonstrators at the end of the project: the first being a tight-fitting T-shirt/base layer, and the second being a bandage that can be worn like a normal support bandage.
His research will receive input and support from industry partners plus academics across the School of MEME.
Dr Dharmasena said: “With this Fellowship, I will be able to address some of the key issues related to wearable health monitoring by creating innovative solutions through nanogenerator technology.
“These ‘super-smart textiles’ developed here will be able to monitor body movements and remotely transmit the sensor signals, while powering their own operations by absorbing energy from the natural motion of the wearer.
He added: “In an era where healthcare access has become critically scarce, the Fellowship outcomes will benefit many people across the globe. In doing so, this work will support in the efforts in addressing global challenges and sustainable development goals in health and wellbeing, and clean energy areas.”
