A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.

Living Electronics: Microbial Metabolism as Batteries, Resistors, and Capacitors

Advanced Electronic Materials, EarlyView.
Three microorganisms are assigned the three elementary roles of a circuit on one sheet of paper. Dormant Bacillus subtilis spores germinate to switch the power source on; a photosynthetic Synechocystis biofilm sets resistance by the color and intensity of light; and a respiring Shewanella oneidensis biofilm stores charge. Together they form a printable
