GETs Revolutionise Personalised Healthcare

GET redefines personalized healthcare
Single-layer graphene tattoos are a rare but unique application used in personal healthcare. It is often used to monitor various electrophysiological signals in humans. They usually have one major problem, their insensitivity to sweat and lack of reproducibility. A group of scientists has developed improved and updated Graphene Electronic Tattoos (GETs) that have improved performance, and are more breathable and durable with increased electronic performance.

The use of metal and silicon-based biomedical devices used to be standard in the medical industry, but today they are increasingly being replaced by extremely light, almost skin-like materials with relatively soft textures that do not disturb their impedance. Such bioelectronic devices have been developed by systematically stacking multiple layers of graphene. Graphene monolayers assembled in tattoos can significantly improve electronic properties. Using this multilayer graphene tattoo stacking structure has resulted in a reduction of skin impedance by two and a half times, a reduction of sheet resistance by up to three and a half times, and a reduction of standard deviation by up to 5 times in previous years. generation.

The first iterations of GETs showed about 85 percent clarity and the ability to hold skin through Van der Waals forces. In addition, GETs exhibit approximately 40% elasticity, which allows uninterrupted easy application to the skin and prevents artifacts caused by strain and induced noise. Although the first designs have satisfactory results, they lack some important aspects, namely surface resistance, interface resistance, and inaccuracies in the optimization of water vapor transmission rate.
