Abstract

A sensor performs medical measurements, particularly pulsoximetric measurements, and is attached or otherwise adhered to a human fingernail or toenail by an inwardly concave, first casing part of a sensor. Electromagnetic, particularly optical, transmitting elements and receiving elements permit the measurement of the radiation reflected by or transmitted through the tissue. The sensor is easy to apply, allows a long application period and is reusable.
