TL;DR: The latest advances in high-efficiency nanostructured energy harvesters and storage capacitors, new sensing modalities that consume less power, low power computation, and communication strategies, and novel flexible materials that provide form, function, and comfort are presented.

TL;DR: The preliminary efforts to achieve a submilliwatt system ultimately powered by the energy harvested from thermal radiation and motion of the body are described with the primary contributions being an ultralow-power ozone sensor, an volatile organic compounds sensor, spirometer, and the integration of these and other sensors in a multimodal sensing platform.

TL;DR: In this paper, a study has been performed to understand the gradual reset in Al2O3 resistive random access memory (RRAM) devices, where a significantly higher number of vacancies are created in the dielectric during the set event.

TL;DR: In this article, a unique tilt target sputtering configuration was employed to produce highly homogenous nanoparticle arrays, with sizes ranging from ∼07 to 134 nm and particle densities of ∼33 −59 cm−2.

TL;DR: In this paper, the authors used small-signal equivalent circuit models and TCAD simulations for trap density estimation in GaN metal-oxide-semiconductor-heterojunction-field effect transistor (MOS-HFET) devices for use in high-voltage power and RF applications.
