Medicine evolved so much this last century. It’s amazing how today we combine medical solutions with technology. So, in not so far future we will be able to monitor all of our body processes with a simple tattoo.
What is even more impressive, we will be able to draw these tattoos on our body. We will need only a pencil and the work will be done.
Future Tattoos: Beneficial For Our Body
A study conducted by the University Of Missouri researchers revealed that paper and pencil can produce a device. This device will be able to help us monitor our health. According to the professor of the College of Engineering Zheng Yan, the devices that already exist are made of two main things: flexible surrounding material and a tracker.
However, to make these types of devices requires spending more money. But, with the new findings, these devices will be way cheaper and simpler to make.
“The conventional approach for developing an on-skin biomedical electronic device is usually complex and often expensive to produce,” he said. “In contrast, our approach is low-cost and very simple. We can make a similar device using widely available pencils and paper.” –said Yan.
The secret lies in the pencils. You probably know that the pencils that we use in our everyday life are made of graphite. If the pencil contains more than 90% graphite, it can release the right amount of energy when you are drawing on a paper. So, the researchers used pencils that contain 93% graphite. Thus, they found that these types of pencils are best for creating a bio-electronics skin device.
So, with these drawings on the skin, we will be able to track our health and provide additional information about our bodies.
“For example, if a person has a sleep issue, we could draw a biomedical device that could help monitor that person’s sleep levels,” he said. “Or in the classroom, a teacher could engage students by incorporating the creation of a wearable device using pencils and paper into a lesson plan. Furthermore, this low-cost, easily customizable approach could allow scientists to conduct research at home, such as during a pandemic.”
Another plus according to professor Yan is that these devices will be biodegradable. The paper will decay in one week, which is not the case with other devices. This is because the commercial biomedical devices contain parts that aren’t biodegradable and don’t break down easily.
