This paper investigates the main factors influencing the design of a vibrotactile feedback device for the human arm. Beside the determination of hardware settings, e.g. vibration motor type (pancake or cylindrical) and intensity threshold, this paper concentrates on the determination of spatial acuity and the division of the arm’s perimeter into sectors which can be distinguished reliably. The ...

A method is described for the measurement of basilar membrane (BM) vibration velocimeter (LDV). The instrumentation was coupled to a compound microscope which served to visualize reflective glass microbeads placed on the BM. The laser beam of the LDV was focused in the microscope object plane and positioned over the reflective bead. We show examples of frequency tuning curves and displacement i...

We are investigating the potential role for vibration response imaging (VRI) in the prompt emergency department (ED) evaluation of patients presenting with dyspnea to aid in differentiation between chronic obstructive pulmonary disease (COPD) and heart failure (HF). VRI is a noninvasive, bedside computer-based technology that creates a visually dynamic two-dimensional image of distribution of v...

We present here a combined theoretical and experimental investigation on effective excitation of microcantilever by using photoacoustic waves. The photoacoustic waves arose from a vibrating Al foil induced by an intensity-modulated laser. We demonstrate that, superior to photothermal excitation, this new configuration avoids direct heating of the microcantilever, thus minimizing undesired therm...

BACKGROUND More and more frequently stress urinary incontinence affects young healthy women. Hence, early implementation of effective preventive strategies in nulliparous continent women is essential, including pelvic floor muscle training. An initial evaluation based on the bioelectrical activity of the pelvic floor muscles (PFM) during whole-body vibration (WBV) would help to devise the best ...
