The invention provides a monitoring device (1) for attachment to a surface of a subject. The device comprises a data collector (2) and a processor (3) as two separate parts which can be detachably joined such that physiological signals which are detected by the data collector can be transferred to the processor for signal processing and provision of monitoring data. At least one of the data collector and the processor comprises a transducer which can convert the physiological signal to a data signal which can be processed electronically. The data collector is adapted for adhesive contact with a skin surface, and may comprise an adapter (6) for the detachable attachment of the processor.

Method and apparatus can be provided according to an exemplary embodiment of the present disclosure. For example, with at least one first section of an optical enclosure, it is possible to provide at least one first electro-magnetic radiation. In addition, with at least one second section provided within the enclosure, it is possible to cause, upon impact by the first radiation, a redirection of the first radiation to become at least one second radiation. Further, with at least one third section of the optical enclosure, it is possible to cause at least one second radiation to be provided to a tissue. For example, the redirection of the first radiation causes, at least approximately, a uniform optical illumination on of a surface of the tissue.

A flexible, optically transparent electrode array comprises at least one graph electrode. The electrode may be positioned on a substrate. The flexible, optically transparent electrode may be used for simultaneous optical imaging and electrophysiological monitoring.

An integrated window for a photosensor for use in an electronic device has first and second transparent regions separated by an opaque region. The first transparent region allows a transmitter to emit light out of the housing of the electronic device and the second transparent region allows a receiver to receive light through the housing. The opaque region is disposed between the first and second transparent regions to isolate them from one another such that the transmitted light is isolated from the received light.
