In this file you will find a brief instruction and additional training materials. Download the PDF file that I have prepared especially for your convenience. I recommend that you complete other lessons presented on the pages of this site in order to learn how to draw a human figure from different angles. So the lesson on how to draw a person from the back came to an end. Take the eraser and carefully remove all the extra lines in your drawing.Ĭolor the hair with any natural shades. With a smooth line, draw the lower outline of the hair and add the spiky strands at the crown.ĭraw smooth lines down from the torso and draw pants.ĭepict smooth lines down from the shoulders and depict arms that fit snugly against the body.ĭraw the short sleeves and add the bottom outline of the clothes.Īt the bottom of the picture draw the shoes, while maintaining symmetry. Draw connecting lines between the head and torso. On the sides of the head add the oval-shaped ears. Furthermore, this low-cost, easily customizable approach could allow scientists to conduct research at home, such as during a pandemic."Īn additional benefit to their approach, Yan said, is that paper can decompose in about a week, compared to many commercial devices that contain components that are not easily broken down.Add the head in the shape of an oval and add the torso in the shape of a rectangle with rounded corners. "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. "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. Yan said the group's next step would be to further develop and test the use of the biomedical components, including electrophysiological, temperature and biochemical sensors. The researchers said their discovery could have broad future applications in home-based, personalized health care, education and remote scientific research such as during the COVID-19 pandemic. Yan said a biocompatible spray-on adhesive could also be applied to the paper to help it stick better to a person's skin. Specifically, the researchers found pencils with 93% graphite were the best for creating a variety of on-skin bioelectronic devices drawn on commercial office copy paper. In the study, the researchers discovered that pencils containing more than 90% graphite are able to conduct a high amount of energy created from the friction between paper and pencil caused by drawing or writing. Since its invention, pencils-made of lead including various levels of graphite, clay and wax-have often been used for writing and drawing. We can make a similar device using widely available pencils and paper." When a healthcare professional draws blood, they insert a small, hollow needle through the skin to access a vein. "In contrast, our approach is low-cost and very simple. It is common for bruising to occur after a blood draw. "The conventional approach for developing an on-skin biomedical electronic device is usually complex and often expensive to produce," he said. Next, from the center axis, go out a full HH and place a mark. The neck and shoulder slopes go a half a HH in the second block. Zheng Yan, an assistant professor in the College of Engineering, said many existing commercial on-skin biomedical devices often contain two major components-a biomedical tracking component and a surrounding flexible material, such as plastic, to provide a supportive structure for the component to maintain an on-skin connection with a person's body. Sketch the head as an oval shape in the first segment in the middle of the first and second lines. Their findings are published in the journal Proceedings of the National Academy of Sciences.
