Shibaura Institute of Technology has developed paper-based wearable sensors that can adapt to body measurements. Patterns printed on paper with a standard inkjet printer enable the material to fold itself into a spiral shape. The copper tape added to the paper serves as an electrode that detects triboelectric signals and measures the galvanic skin response. The method aims to enable the quick and easy production of low-cost, customized sensors.
Why it matters
This approach offers a more practical framework for the design and production of wearable sensors that can be adapted to individuals. The material’s ability to take shape according to the body is significant for applications in which the fit between the measurement surface and the skin is important. The detection of triboelectric signals and the ability to measure the galvanic skin response make it possible to monitor different electrical data in a single wearable structure. For this reason, the development is relevant to research and design teams seeking low-cost and customizable sensors. However, how reliably the method will work across different body measurements, how durable the paper structure will be during use, and how consistent the measurements will remain are questions left unanswered in the text.
