Designers have shown that simply pencils and paper could produce bioelectronic devices with potential for monitoring health and wellness.
Someday, individuals could monitor their own health and wellness problems by simply getting a pencil and drawing a bioelectronic device on their skin, they say.

Many current industrial on-skin biomedical devices often include 2 significant components—a biomedical monitoring element and a bordering versatile material, such as plastic, to provide a helpful framework for the element to maintain an on-skin link with a person's body, says Zheng Yan, an aide teacher in the College of Missouri University of Design.
"The conventional approach for developing an on-skin biomedical digital device is usually complex and often expensive to produce," he says. "On the other hand, our approach is inexpensive and very simple. We can make a comparable device using commonly available pencils and paper."
In the study, the scientists found that pencils containing greater than 90% graphite can conduct a high quantity of power that outcomes from the rubbing in between paper and pencil. Particularly, the scientists found pencils with 93% graphite were the best for producing a variety of on-skin bioelectronic devices attracted on industrial workplace copy paper. Yan says a biocompatible spray-on sticky could also be used to the paper to assist it stick better to a person's skin.
The scientists say their exploration could have wide future applications in home-based, personalized healthcare, education and learning, and remote clinical research such as throughout the COVID-19 pandemic. Yan says the group's next step would certainly be to further develop and test the use the biomedical elements, consisting of electrophysiological, temperature level, and biochemical sensing units.
"For instance, if an individual has a rest issue, we could attract a biomedical device that could help monitor that person's rest degrees," he says. "Or in the class, a instructor could involve trainees by integrating the development of a wearable device using pencils and paper right into a lesson plan. Additionally, this inexpensive, easily adjustable approach could permit researchers to conduct research in your home, such as throughout a pandemic."
An extra benefit to their approach, Yan says, is that paper can decompose in about a week, compared with many industrial devices which contain elements that are not easily broken down.
