RF Magnetron Sputtered Tungsten Disulfide Films: Influence of Target Preparation, Deposition Parameters, and Storage Conditions on Thin Film Stoichiometry

Advanced Materials Interfaces, EarlyView.
Sputtered WS2 films were investigated in terms of their S‐ and O‐concentration depending on deposition power and pre‐sputter time. Chemical and structural investigations were done using EDS, TEM, SEM, AFM, XRD. In general, 20 W films exhibit a wide variation in stoichiometry and structure whereas 80 W films demonstrate a higher S/W ratio than 20 W ...

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

Advanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

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 ...
