Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Grain Boundary Sliding Kinetics and Stress Relaxation Phenomena in Ni Alloys
, 1991 Internal friction measurements have been performed on Ni-20 wt% Cr alloys containing trace additions of Ce ranging from 0 to 180 at ppm, in order to determine grain boundary sliding kinetics and associated stress relaxation phenomena.

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant
Advanced Materials Technologies, EarlyView.A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Direct Measurement of Grain-Boundary Sliding in Forsterite Bicrystals
Olivine is the most abundant mineral in Earth’s mantle, and its rheological behaviour is likely to control upper-mantle deformation. While the rheological behaviour of olivine is widely studied, relatively little is known about the behaviour of

Advanced Materials Technologies, EarlyView.Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Superplastic-like flow in a fine-grained equiatomic CoCrFeMnNi high-entropy alloy
Materials Research Letters, 2017 A CoCrFeMnNi high-entropy alloy (HEA) showed elongation to failure ∼320% at T = 1023 K and a strain rate $ \dot \varepsilon = {10^{ - 4}}\, {{\rm s}^{ - 1}} $ .
