The field of medicine has evolved significantly, in part, due to advances made in other realms of modern technology. One such example includes health microsystems, where small-scale measurement devices, integrated with electronic support circuitry, are microfabricated for use in-home or in clinical/hospital settings.

Abstract
The field of medicine has evolved significantly, in part, due to advances made in other realms of modern technology. One such example includes health microsystems, where small-scale measurement devices, integrated with electronic support circuitry, are microfabricated for use in-home or in clinical/hospital settings. Silicon micromachining technology has allowed fabrication of novel, miniaturized sensors leading towards innovative applications in next generation, portable analysis and diagnostic instruments. This paper reports on the development of a silicon flow microsensor which, in conjunction with a pressure microsensor, is used for real-time urodynamic evaluation of urinary dysfunction. It is known that variations in urodynamic pressure-flow patterns can be used to differentiate between constrictive and compressive obstructions by simultaneously measuring both bladder pressure and urine flow rate as a function of time. This device can allow for convenient, year long in-home monitoring, allowing an urologist to subsequently assess potential urinary dysfunction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
