Self‐Powered All‐in‐One Wearable Bioelectronics Driven by Pneumatic Energy Buffering of Daily Footsteps

open access: yesAdvanced Science, EarlyView.
A pneumatic energy‐buffering strategy transforms transient and intermittent footsteps into quasi‐continuous electrical energy for a self‐powered wearable biosensing platform. The footwear‐integrated air‐pumping harvester, combined with the rationally designed power‐management system, powers a wearable ankle PPG device with reduced motion artifacts ...

Geogrid in Flexible Pavements

Transportation Research Record: Journal of the Transportation Research Board, 2008
Full-scale accelerated testing was used to provide new insight into quantifying the effectiveness of geogrids on low-volume flexible pavement performance. Although several previous studies report that geogrids improve pavement performance by enhancing structural capacity and reducing distress potential, the new study addresses how to maximize the ...

Perpetual pavement design for flexible pavements in the US

International Journal of Pavement Engineering, 2006
Long lasting asphalt pavements have been designed and constructed in the United States for many decades. Pavements that have avoided structural failure in the presence of heavy traffic and which require only periodic resurfacing are advantageous in terms of minimizing life cycle cost and user delays.
