Smart clothing is a very promising market, and even health monitor and LED display technology can be integrated into smart clothing. However, most of today's smart textiles are too stiff and expensive and are not suitable for practical wearable garments.
According to foreign media reports, a new study by the Cambridge Graphite Center (CGC) and Jiangnan University may change this situation. Scientists have developed conductive fabrics containing graphene that can solve the problem of smart garments that are not soft enough and are inexpensive.
Scientists have chemically changed the internal structure of graphene and developed a graphene flake that is indistinguishable from cotton fabrics. The results are shown through a wearable motion sensor. After testing, this wearable intelligent fabric was able to make 500 turns in the washing machine without any loss.
At present, researchers have developed smart clothing with graphene pressure sensors and heart rate sensors that can collect physical health data such as heart rate and blood oxygen. In the future, our clothes will be connected to the mobile phone via Bluetooth. We do not need other smart wearable devices to collect our own health conditions.
The most important feature of graphene is its thermal and electrical conductivity. Some clothing that can generate electricity has already appeared on the market. This kind of smart textile has a photovoltaic material or a mobile power generation device. When our mobile phone needs to be charged, clothes can act as mobile power supply. The thermal conductivity of graphene can also provide the infrared physiotherapy function to the human body. With it, you don't need to wear it thick in winter.
Graphene fabric may be the future of wearable devices
Graphene is a two-dimensional crystal having a single-layered atom thickness that is separated from a graphite material and composed of carbon atoms. Graphene is based on carbon and has great potential in various fields such as battery technology, computer chips, electric vehicles, and airship manufacturing. Because it is only nanometer thick, it is very flexible, bendable, and has good thermal conductivity and ruggedness. These characteristics make graphene the key to future breakthroughs in wearable devices.
In 2004, physicists Andre Gemm and Konstantin Novoselov of the University of Manchester in the United Kingdom discovered graphene and won the 2010 Nobel Prize. Since then, graphene has become one of the most sought-after materials in the 21st century. It has also been known as “black gold†and “king of new materialsâ€. It has even been suggested that graphene will become a substitute for silicon.
