Biodegradable Circuit Printing Pen CircuitPen Launches: Hand-Draw Electronics on Any Surface

CircuitPen uses conductive bio-ink to directly draw functional circuits on paper, fabric, skin, and other surfaces, naturally degrading after 24 hours.

Cambridge University spinoff CircuitInk released CircuitPen on February 27 — an electronic circuit drawing tool that resembles an ordinary marker pen. The pen uses a proprietary conductive bio-ink, allowing users to draw conductors, resistors, and simple logic gates directly on paper, fabric, or even skin.

The pen tip contains a pressure sensor that recognizes writing pressure and automatically adjusts ink flow. Through the companion smartphone app, users can design circuit sketches on paper while the app detects in real time whether circuit connections are correct.

CircuitPen retails for $49, with refill cartridges capable of drawing approximately 50 meters of conductor. The product currently targets the education market and rapid prototyping scenarios.
