Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

open access: yesAdvanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Flexural Fatigue Strength of Plain Concrete

open access: yesACI Materials Journal, 1993
This paper presents a new expression to describe the flexural fatigue strength of plain concrete. It incorporates the effects of stress ratio and stress level into the faitgue equation and allows a statistical description of fatigue life in terms of both stress level and stress ratio. A concept of equivalent fatigue life is introduced in the derivation
