The technology

By employing sustainable design techniques, we have developed an innovative paper-based pressure sensor – the world's first of its kind. Our PaperWeight Digital™ technology combines patented cellulose-based electronics with advanced, low-waste printing methods to create a responsive smart surface that detects pressure, weight, and touch.

These devices can be cost-effectively manufactured on a large scale using Sheet-2-Sheet or Roll-2-Roll processing. Furthermore, the sensor's shape, size, functionality, and connectivity can be easily adapted to various use cases.

What makes it so special?

PaperWeight Digital™ delivers robust, customizable, and simple-to-install load and touch sensors that are made almost entirely from paper or other sustainable materials.
