    As we begin to see what could be the end of the silicon revolution and a transition to a nanotechnology/carbon based electronics era, it is clear that we need to develop new measurement techniques and tools. The continued scaling of electronics creates new problems that must be measured and understood before any kind of commercialization and mass production can take place. Using the measurement triad of DC I-V, CV, and the new Ultra-fast I-V provided in the aforementioned characterization tool increases the potential for new discoveries to be made in the challenging world of semiconductor scaling and nanoscience.

    In this paper the importance of microprocessor and IC device reliability is discussed and how modifying the operational parameters of these devices through over-and under-clocking can either reduce or improve overall reliability, respectively, and directly affect the lifetime of the system in which these devices are installed.

  • Automatic noninvasive measurement of arterial blood pressure

    This paper discussed arterial blood pressure measurement. Because of the high rate of hypertension in the adult population and its harmful effects, the measurement of arterial blood pressure is of great clinical significance. Manual sphygmomanometry, developed more than a hundred years ago, is currently the most accurate non-invasive technique for arterial blood pressure measurement. Since manual sphygmomanometry requires a well-trained examiner, only single measurements of blood pressure will generally be performed by a physician during a given visit. This single measurement only provides partial information since blood pressure changes spontaneously. The available automatic blood pressure meters, mainly based on oscillometry, can be used at home but some of them are of low accuracy. A direct technique for the measurement of systolic blood pressure by means of the detection of the blood pressure pulses' reappearance during cuff deflation has the potential to provide accurate automatic measurement of systolic blood pressure.

    Magnetic fluids are formed when magnetic particles are dispersed in a carrier liquid and suitably coated [1], [2]. Coating the particles provides an elastic shield which avoids particle friction, and it can be also used to implement bio-assay strategies. There are two types of magnetic fluids: magneto-rheological fluids and ferrofluids. The size of the dispersed particles is what distinguishes the two types of magnetic fluids: magnetorheological fluids containing magnetic particles with a diameter on the order of microns and the fluids change from a liquid to a solid in response to a high magnetic field while ferrofluids are colloidal suspensions of magnetic nanoparticles that maintain their liquid state in the presence of a strong magnetic field. In the case of ferrofluids, the higher the magnetization strength, the greater the magnetic pressure exerted by the fluid [3]. Magnetic fields applied to a ferrofluidic volume and the consequent magnetic force causes the alignment of the ferrofluidic particles in the direction of the field and modifies the viscosity and the control of the ferrofluid mass position. Interest in ferrofluids and magnetic particles exists because of the possibility of efficiently converting valuable elastic energy into mechanical energy in many applications. In this column, we describe some of the uses of ferrofluids and highlight ways to exploit its ferrohydrodynamic instabilities. View full abstract»
