Abstract

Position detection is a key function needed for monitoring patients with sleep-related movement disorders. Tools are urgently needed to obtain a detailed patient-friendly long-Term assessment of sleep-related movements in the home situation. We present an optical two-dimensional pressure sensing system for real-Time patient monitoring that is based on optical coupling between crossing polymer or plastic optical fibres (POFs) and can easily be placed under a mattress in a home environment. Because the system deploys a grid of standard 1 mm diameter Step Index PMMA POF, it is low-cost, robust, flexible, compact, waterproof, scalable, not affected by external electrical fields, nor does it generate any electrical fields. Moreover, an alternative simple pressure sensitive POF crossing construction, based on local fibre bending is presented, which is more sensitive and more robust than crossing fibres left intact.
