Hierarchically Wrinkled Silver Ink as a Platform for Fully Integrated Stretchable Electronic Systems
Advanced Materials Technologies, EarlyView.Silver Hierarchical Responsive ink (SHRink), a universal approach for the fabrication of highly stretchable interconnects, wirings, and skin‐interfaced electrodes, is realized through low‐cost, scalable spray‐printing and transfer‐printing. The SHRink demonstrates high electrical conductivity (1.2E04 S cm−1) and large stretchability (235% max fracture ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control
Advanced Materials Technologies, EarlyView.A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Advanced Materials Technologies, EarlyView.Optically pumped magnetometers are employed to contactlessly map the spatiotemporal dynamics of the magnetic field linked to electrical activity of a skeletal muscle in vivo. It is demonstrated that localization of the clinically relevant innervation zone is feasible using this non‐invasive magnetic measurement modality. ABSTRACT Magnetomyography (MMG)

Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2010 Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. Sintering is a process which occurs
