TL;DR: This work has engineered individual biomolecular motors and nanoscale inorganic systems, and their integration in a hybrid nanomechanical device powered by a biomolescular motor is described.

TL;DR: In this article, a pseudo-2D surface potential model for the double-gate tunnel field effect transistor (DG-TFET) is presented, where the depletion regions induced inside the source and drain are included in the solution and these regions become critical when scaling the device length.

TL;DR: In this article, a fabrication technology for silicon-based neural probe devices and their assembly into two-dimensional and three-dimensional microprobe arrays for neural recording is presented. But the fabrication is based on robust double-sided deep reactive ion etching of standard silicon wafers and allows full 3D control of the probe geometry.

TL;DR: In this article, the authors used X-ray radiographs of the exploding wire plasmas using 2.5-10 keV photons from a Mo wire X-pinch backlighter enabled measurements of areal densities of W ranging from 2×1017/cm2, equivalent to 0.03 μm of solid density W, to about 1019/cm 2.

TL;DR: In this paper, a novel high-density CMOS-based silicon microprobe array for intracortical recording applications is presented. But instead of performing a mechanical translation of the probe shaft relative to the brain tissue to optimize the distance between electrodes and neurons, the electrode position is adjusted by electronically switching between the different electrodes along the shaft.
