The story of a simple pencil began several centuries ago. All this time it was only used for drawing and writing. Recently a team of researchers found that using the graphite part of a pencil, and plain paper you can make an inexpensive biometric sensors to track health.
A simple pencil consists of 90% graphite. As it turned out, while drawing enough heat energy to create on plain paper sensors for bioelectric monitoring. According to experts, with pencil and paper, it will be possible to monitor temperature, glucose levels and other indicators of the body.
“If a person has trouble sleeping, we can draw a biomedical device that will monitor his sleep. Or in the classroom, the teacher can engage students by enabling the creation of wearable devices using pencils and paper to the lesson plan. In addition, this inexpensive and easily configurable approach may allow scientists to conduct research at home, for example, during a pandemic,” summarize the researchers.
The new technology has a distinct advantage in ease of use and low cost. In addition, the materials used have minimal environmental impact, since it decays rapidly. Also significant advantage is called the paper that you can fold, carry and even use again. Additionally, States that are best suited the pencils with 93 percent graphite content.
