Miniaturized sensor for physiological pressure measurements |
摘要 |
Miniaturized sensor for physiological pressure measurements in situ, including an elastic sleeve (1) with a diaphragm portion through which the hydrostatic pressure is transmitted as a force acting on a light conductor (2) which is supplied with light from an external source and fixed to a support body (3) such that the hydrostatic pressure variations cause elastic, relative positional variations between the end surface (4) of the light conductor (2) and a light-reflecting surface (5) on the support body (3), which in turn gives rise to variations in reflected light intensity transmitted back through the light conductor (2), to serve as a pressure signal.
