Few rotational actuators currently exist with the ability to transmit motion at different speeds, torques, and directions at the nanometer scale. We present work regarding the application of helical nanobelts as linear-to-rotary and rotary-to-linear motion converters. We discuss their ability to rectify device rotation to linear motion for untethered microrobotic applications as well as their application...
In this paper, we report an in-situ nanosoldering technique to make electrically conductive interconnections between three-dimensional (3D) helical micro-/nanostructures and electrodes for the nanorobotic assembly of nanoelectromechanical systems (NEMS) using gold nanoparticle ink. 3D helical nanobelts are placed onto pre-fabricated gold electrodes using nanorobotic manipulation inside a scanning...
We present the use of integrated semiconductor nanocoils for conductometric sensors. The three-dimensional structures are made of an n-type InGaAs/GaAs bilayer. They are suspended over the chip surface and connected to one electrode on each side. The process is based on conventional batch microfabrication techniques. Process and design features that are critical for the realization of this type of...
