Vibration levels exposed at speed bump and speed hump transitions

, 2022
The method used to eliminate the adverse effects of excessive vehicle speed in traffic operation is speed management. In the study, speed control undulations (SCUs), as one of the crucial tools of speed management in urban areas, have been evaluated in terms of their discomfort to the drivers and passengers in the passes over.

Engineered Strain in 2D Materials by Direct Growth on Deterministically Patterned Grayscale Topographies

Advanced Science, EarlyView.
ABSTRACT Strain is a proven technique for modifying the bandgap and enhancing carrier mobility in 2D materials. Most current strain engineering techniques rely on the post‐growth transfer of these atomically thin materials from growth substrates to target surfaces, limiting their integration into nanoelectronics.

Highly Aligned Bacteria Cellulose Yarn Aggregation for Energy Generation and Strain Sensing

Advanced Science, EarlyView.
Although high‐performance bacterial cellulose fibers have attracted significant interest for wearable electronics, a self‐powered and high‐mechanosensitive design is still scarce for achieving an intelligent integrated system. Here, we demonstrate an innovative bio‐fabrication strategy to develop a core‐sheath yarn that features the ordered network and
