Kurzfassung englisch:
Magneto-elastic bilayers (BLs), consisting of a magnetostrictive layer and a non-magnetic counter layer show highest sensitivity with respect to bending. This paper describes a biomedical application in the field of sleep apnea screening. A multi-parametric detector fixed at the skin of the thorax contains two BLs. One BL yields a skin curvature sensor (SCS) adjusting itself to curvature variations as resulting from physiological activities. The second BL exhibits a free end thus working as a motion sensor (MS). The two signals are fed into artificial neural networks (ANNs) for the detection of short time events. In particular, the SCS yields events like normal respiration, obstructive snoring or cessation of respiration. The MS yields events like body movements, back position or side position. Simple algorithms are planned to be used to interpret these events with respect to obstructive or central apnea.
