International ClassA61B 005/00AbstractA conformable sensor which uses a flexible substrate, preferably a polyester strip is disclosed. The emitter and detector are mounted on one portion of the strip with conductive traces connecting to them. The second portion of the strip is folded over to cover the emitter and detector and traces, with openings for the emitter and detector. A conductive coating is applied to the strip to provide shielding from electromagnetic interference. Preferably, a second portion of the strip, which folds over the first portion, also has a Faraday shield covering the opening over the detector. The detector and emitter semiconductor chip die (rather than use encapsulated chips) may be mounted directly on the polyester strip so that it is in contact with one of the conductive traces. | |
