We report on fabrication and experimental characterization of a linear Brownian motor with a periodic 3-phase electrostatic rectification for unidirectional transport of nanobeads in microfluidic channels. The transport of the beads is performed in 1 μm deep, 2 μm wide PDMS microchannels, which constrain three-dimensional random motion of nanobeads into 1D(More)
This paper reports for the first time on net-unidirectional transport of nanobeads by Brownian motion using a periodic 3-phase electrostatic rectification. The transportation of beads is performed in 1 μm deep, 2 or 3 μm wide PDMS microchannels, which constrain three dimensional random motion of nanobeads into 1D fluctuation, so-called tamed Brownian(More)
Nanosystems operating in liquid media may suffer from random Brownian motion due to thermal fluctuations. Biomolecular motors exploit these random fluctuations to generate a controllable directed movement. Inspired by nature, we proposed and realized a nano-system based on Brownian motion of nanobeads for linear transport in microfluidic channels. The(More)
Linear Brownian motors utilize relatively weak electric fields to bias the diffusion of particles in a microfluidic channel thereby harnessing Brownian motion to facilitate particle transport. We present a custom simulator for such a system and use it to optimize transport by modifying the electrode configuration and rectification scheme. With insight(More)
We propose a highly wearable, upper-arm type, oscillometric-based blood pressure monitoring technology with low-stress. The low-stress is realized by new developments in the hardware and software design. In the hardware design, conventional armband; cuff, is almost halved in volume thanks to a flexible plastic core and a liquid bag which enhances the(More)
This paper presents the rotation of a silicon nanoneedle fueled by Brownian motion which may lead to a new class of thermo-mechanical nano-motors. A nanoneedle with a magnetic bead at one end is immobilized at the end by a permanent magnet in the water and its rotational Brownian motion is observed. DRIE of a silicon substrate with magnetic nanobeads as the(More)
