A MEMS Electromagnetic Vibration Energy Harvester with Monolithically Integrated NdFeB Micromagnets
Advanced Materials Technologies, EarlyView.50µm thick sputtered arrays of NdFeB micromagnets are directly integrated into a functional MEMS in‐plane electromagnetic vibration energy harvester. A combination of analytical modeling and numerical simulations guided the design of the magnet arrays and ad‐hoc coil, to produce a high transduction factor.

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
Advanced Materials Technologies, EarlyView.This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...
