Liquid Crystal Elastomer Actuator Matrix for Large Area Applications
Advanced Materials Technologies, EarlyView.A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Biodegradable and Edible Milli‐Fluidic Logic Circuits
Advanced Materials Technologies, EarlyView.Fully biodegradable and edible fluidic circuits are developed using gelatin‐based valves that operate at low pressure. Logic gates, a one‐bit memory, and a ring oscillator are demonstrated, showing that biodegradable materials can perform computation and control.

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)

Emerging technologies for the integration of flexible electronics into Heart-on-a-Chip platforms
Journal of High School ScienceThe integration of flexible and stretchable electronics into Heart-on-a-chip (HoC) platforms presents remarkable opportunities for mimicking the mechanical and electrophysiological microenvironment of native cardiac tissue. Conventional rigid electronic systems fail to accommodate the dynamic, soft, and anisotropic properties of the beating heart ...
