It turns out that pencils containing more than 90% graphite are great conductors. At the University fo Missouri researchers have found that pencisl with 93% graphite could create on-skin bio-electronic devices. Here’s more from SlashGear:
Biocompatible spray-on adhesive to be applied to the paper that would stick to the person’s skin. The team believes that the discovery could have broad applications in the future for home-based, personalized healthcare, education, and promote scientific research. Biomedical components, such as electrophysiological, temperature, and biochemical sensors.
The team believes in the future that people with a sleep issue, for instance, would be able to draw a biomedical device that could monitor sleep levels. Teachers in the classroom could engage students by incorporating the creation of wearable devices using pencils and paper into a lesson plan.
