Researchers at the University of Missouri have demonstrated an exciting combination of pencils and paper that can be used to draw devices to monitor people’s personal health at home. At present, a lot of research is looking at how to use flexible electronics and sensors that are wearable to capture health-related information.
In the study, the researchers found that pencils containing more than 90 percent of graphite produce a lot of energy when rubbing between paper and pencil when they are painted or written. The team found that pencils containing 93% graphite were best suited for bioelectronic devices drawn on a variety of skins drawn on commercial office photocopiers. Apply biocompatible spray adhesives to paper that can stick to human skin. The team believes the discovery could be used in the future in the areas of family, personalized medicine, education, and scientific research. Biomedical components such as electrophysiological, temperature, biochemical sensors, etc.
The team believes that in the future, a biomedical device that can monitor sleep levels could be drawn on paper to help sleep-related users. In the classroom, teachers can include wearables made from pencils and paper into their curriculum to engage students. Another major benefit is that the paper used to create the sensor breaks down within a week. Many commercial devices that contain sensor components are not easily decomposed. Non-decomposable equipment can have a significant impact on medical waste and landfills. It is unclear when or whether the technology will reach commercial applications.
