Protein-based next generation electronics

Introduction

Recently, an entirely novel type of bacteria has been discovered that can guide high electrical currents over centimeter-long distances through long, thin fibers embedded in the cell envelope.

Electrical Properties

Recent studies by PRINGLE consortium members reveal that these protein fibers possess extraordinary electrical properties, including an electrical conductivity that exceeds that of any known biological material by orders of magnitude.

Project Ambition

The ambition of PRINGLE is to unlock the vast technological potential of this newly discovered biomaterial. To this end, we propose to utilize custom-crafted protein structures as elementary active and passive components in a new generation of biocompatible and biodegradable electronic devices.

Long-term Vision

The resulting long-term technological vision is to establish a radically new type of electronics (PROTEONICS) that is entirely bio-based and CO2 neutral, in which protein components can provide different types of electronic functionality.

Objectives

PRINGLE will provide the fundamental and technological basis for PROTEONICS by:

1. Developing fabrication and patterning technologies for proteonic materials and nanostructures.
2. Tuning the electronic properties of these proteonic materials in a fit-for-purpose manner.
3. Integrating proteonic materials as functional components into all-protein electronic devices.

Impact

As such, PRINGLE-based technology could provide a significant breakthrough towards next-generation electronics applications in a circular economy, opening entirely new avenues for interfacing biological systems with electronics and allowing completely new sustainable production and recycling pathways for electronic components.
