As we approach the spring of 2026, researchers at Binghamton University and the University of Utah have refined the "Papertronic" concept. It is vital to note: while these biobatteries are revolutionary for low-power sensors, smart bandages, and environmental trackers, they cannot yet provide the high-density energy required for smartphones or electric vehicles.

As we move into the spring of 2026, the EU project HyPELignum and researchers at the University of Glasgow have moved the needle on sustainable hardware. It is critical to note: while wood-based and silk-based PCBs are currently being integrated into low-power devices like computer mice and RFID tags, they are not yet robust enough for high-heat servers or smartphone processors.

The move toward Liquid Metal Alloys (LMAs)—specifically Eutectic Gallium-Indium (EGaIn) and Gallium-Indium-Tin (Galinstan)—is the latest "Post-Metal" concept being floated for high-end manufacturing. It is vital to note: while these alloys are used in high-end lab applications and specialized cooling systems, they are not yet available on the shelf for consumer electronics manufacturers.
