In Indiana, a team of researchers at Purdue University has developed biodegradable, paper-based sensors that could one day help doctors track patients with chronic diseases or after surgery.

The device attaches to the skin, and because it is made from paper-based cellulose, is cheap and biodegradable.

“The low cost of these wearable devices and their compatibility with large-scale manufacturing techniques will enable the quick adoption of these new fully disposable, wearable sensors in a variety of healthcare applications requiring single-use diagnostic systems,” says Ramses Martinez, a professor of industrial and biomedical engineering at Purdue and leader of the research.

The work was published in a recent issue of ACS Advanced Materials and Interfaces.
