Architectural Tuning of Bouligand Electrospun Laminates Enables Coupled Mechanical Robustness and Electromechanical Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired Bouligand architectures are translated into biodegradable polymer laminates with integrated sensing, revealing how structural design governs multifunctional performance. A 20° interlayer rotation optimizes strength, flexibility, and electromechanical response, while embedded nanotube networks enable real‐time damage detection and wearable ...

Investigating temporary architecture(s)

open access: yes, 2006
Architecture has always been associated with the qualities of permanence and timelessness. The thesis investigates the notions of temporality and permanence in relation to the built environment. It recognizes that in the ever changing dynamic flux of the

Dynamic Physicochemical Gradients for Tendon–Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
Dynamic physicochemical gradients offer a framework for reconnecting soft tendon and hard bone. This Review examines how hydration, transport, loading and degradation reshape these gradients during healing. Coordinating regional biological cues with progressive transfer of load from scaffold to tissue guides the design of interfaces that retain ...
