Wearable tech has been a slowly rising trend over the past decade. Most wearables these days are health-related, and tracking the body is a difficult task. We’ve seen tech such as sleep trackers and fitness trackers prove beneficial for consumers, but wearables have yet to achieve their full potential. With graphene, that may just become possible.
Graphene is well-known as a “wonder material,” and looking at its properties, it’s easy to see why. Graphene is one of the thinnest materials known to man; it is made up of a single layer of carbon atoms, all connected and interlaced into a lattice, honeycomb-like formation. In addition to being thin, graphene is also incredibly light. But don’t let its size fool you — it’s nearly 200 times stronger than steel, and possess technological capabilities far beyond our current materials provide.
Graphene is excellent at conducting heat and electricity, and the material is a frontrunner in replacing copper and silicon in tech devices. For instance, graphene is particularly good as a sensor, and is being researched for a variety of sensor types, including for gas, DNA, pH levels, environmental contamination, pressure, and more.
Graphene can also potentially impact wearables by powering them for greater capability and lasting power. Using graphene to create next-gen flexible batteries, University of Glasgow researchers have successfully created a graphene supercapacitor that is capable of recharging using solar power and discharges enough energy to power advanced wearable devices.
The most recent and perhaps most important breakthrough in graphene wearables to date were featured at the 2019 Mobile World Congress (MWC) in their Graphene Pavillion. Research nonprofit organization ICFO presented revolutionary graphene-based health-monitoring wearables; these devices are less like the watches and bands that currently occupy much of the wearable tech space, and instead acts like a dermal patch. This means that the graphene wearable can be applied directly to the skin, which can result in improved readings when monitoring health metrics.
ICFO supposes that this graphene tech would be useful in monitoring hydration and blood oxygen levels. This would be particularly helpful for when people are in extreme conditions, such as at the Earth’s poles, high altitudes, or anywhere far from civilization. In such situations, someone could apply the patch, which would use graphene to create miniscule sensors, circuits, and batteries to power the wearable and allow it to track internal data.
The patch would then be paired with a smartphone to allow for real-time communication, and will notify users when they are at risk of dehydration or other severe medical statuses. The patches will also be made to be disposable, and the researchers at ICFO are working to ensure that all components, even necessary adhesives, are biodegradable and environmentally friendly.
With the newly revealed patch-like wearable, graphene is beginning to show the world how it can disrupt various tech-based industries, and the healthcare and medical fields are sure to benefit from graphene research. With the wonder material in its hands, the wearable tech industry is sure to continue making leaps and bounds moving forward.
