Cellulose and lignin are the two most abundant biopolymers on earth. These materials offer structural integrity and electrochemical functionality for efficient energy technologies, especially for energy scavenging and electrical energy storage. Here, piezo-electric energy generators and printed batteries are reported, targeting sustainable manufacturing, circularity, and energy efficiency. In addition, a printable organic electronic complementary circuit technology has been developed enabling low-power operation at voltages that are compatible with bio-based organic batteries. Together, these devices and circuits provide a platform for future internet of things solutions, specifically targeting sustainable production and materials, and an easy end-of-life handling.
