This paper reports our work on developing a surface tension actuated micro-robotic platform supported by three bubbles (liquid environment) or droplets (gaseous environment). The actuation principle relies on the force developed by surface tension below a millimeter, which benefits from scaling laws, and is used to actuate this new type of compliant robot. By separately controlling the pressure...

A device that provides quantitative assessment of the grasping function and allows grasping function improvements to be monitored over time can potentially be very useful for hand surgeons, physiotherapists and occupational therapists. A Dynamic Grasping Assessment System (DGAS) that is capable of measuring finger forces during wrist extension, flexion, adduction and abduction was developed. Th...

There is a scarcity of research on whole body vibration exercise and resistance exercise as a combined program for children and adolescents with type I Osteogenesis Imperfecta (OI). Type I OI is the mildest and most common form, characterized by mild to moderate fragility without bone deformity. The goal of treatment when working with people with Type I OI is to reduce the risk of fractures pri...

Coulter counters measure the size of particles in solution by passing them through an orifice and measuring a resistive pulse, i.e., a drop in the ionic current flowing between two electrodes placed on either side of the orifice. The magnitude of the pulse gives information on the size of the particle; however, resolution is limited by variability in the path of the translocation, due to the Br...

We report our studies on the time-resolved dynamics of the superconducting-to-resistive transition in dcbiased epitaxial YBa2Cu3O72x ~YBCO! microbridges, excited by nanosecond-long current pulses. Our experimental structures consisted of 200-nm-thick epitaxial YBCO films deposited on MgO substrates. They were patterned into a single 25 mm by 50 mm microbridge, embedded in the middle of a coplan...

Task failure during inspiratory resistive loading is thought to be accompanied by substantial peripheral fatigue of the inspiratory muscles. Six healthy subjects performed eight resistive breathing trials with loads of 35, 50, 75 and 90% of maximal inspiratory pressure (MIP) with and without supplemental oxygen. MIP measured before, after, and at every minute during the trial increased slightly...

We discuss Brownian motion from the more elementary viewpoint presented by Einstein in 1908. Later developments and applications are briefly reviewed. One of the celebrated papers of 1905 deals with a quantitative study of the random motion.A couple of years later Einstein wrote a simplified account of the seminal work and we will present this version in this article. A direct test of the molec...
