Temperature Homogenization of Co-Integrated Shape Memory—Silicon Bimorph Actuators

The high work density and beneficial downscaling of shape memory alloy (SMA) actuation performance provide a basis for the development of actuators and systems at microscales.

Integration of AlN piezoelectric thin films on ultralow fatigue TiNiCu shape memory alloys

Biomagnetic field sensors based on AlN/FeCoSiB magnetoelectric (ME) composites desire a resonant frequency that can be precisely tuned to match the biomagnetic signal of interest.

TiNiHf/SiO2/Si shape memory film composites for bi-directional micro actuation

The martensitic phase transformation in Ti40.4Ni48Hf11.6 shape memory alloys is leveraged for bi-directional actuation with TiNiHf/SiO2/Si composites. The shape memory properties of magnetron sputtered Ti40.4Ni48Hf11.6 films annealed at 635°C – 5 min are influenced by film thickness and the underlying substrate.

Shape Memory Alloy Thin Film Auxetic Structures

Auxetic structures provide an interesting approach to solving engineering problems due to their negative Poisson’s ratio, which allows for elongation perpendicular to applied stresses, opposite to a conventional structure’s necking behavior. 

Thin-Film Superelastic Alloys for Stretchable Electronics

Conductive serpentine interconnects comprise fundamental building blocks (e.g., electrodes, antennas, wires) of many stretchable electronic systems. Here we present the first numerical and experimental studies of freestanding thin-film TiNiCuCo superelastic alloys for stretchable interconnects.

Auxetic Superelastic TiNiCuCo Sputtered Thin-Films For Stretchable Electronics

Auxetic shape memory alloy (SMA) materials offer many opportunities for ballistics1, deployable antennas2, actuators, stretchable electronics3–5, and biomedical devices6, 7. Auxetic materials are periodic structures characterized by a negative Poisson’s ratio, meaning they expand laterally when stretched longitudinally.

Structural Anisotropy in Stretchable Silicon

Patterned planar silicon (Si) semiconductor structures able to conform around 3D surfaces are promising candidates for wearable devices from solar cells to displays. Despite the known anisotropic material properties of crystalline semiconductors, prior evaluations have assumed isotropic stretchable mechanical behavior.

Power Optimization of TiNiHfSi Shape Memory Microactuators

We present a novel design approach for the power optimization of cantilever-based shape memory alloy (SMA)/Si bimorph microactuators as well as their microfabrication and in situ characterization.
