Abstract: An embodiment of a photovoltaic cell forms a barrier layer over a flexible substrate and forms a plurality of parallel lines of N-type semiconductor material directly on the barrier layer. A plurality of parallel lines of P-type semiconductor material are formed directly on the barrier layer and positioned with each line of the plurality of parallel lines of P-type semiconductor material having at least one common longitudinal boundary with one line of the plurality of parallel lines of N-type semiconductor material. A plurality of first conductive bus lines are in longitudinal contact with at least a subset of the plurality of parallel lines of N-type semiconductor material, and a plurality of second conductive bus lines are in longitudinal contact with at least a subset of the plurality of parallel lines of P-type semiconductor material.

Abstract: A non-invasive fetal probe having enhanced adhesion and electrical isolation for attaching to the presenting part of a fetus and sensing at least one fetal parameter during labor and delivery. In one embodiment of the present invention, the electrical isolation of the fetal probe includes a non-conductive element used in combination with various conductive assemblies made from gel formulations which are polymerized to form a fetal sensor. The non-conductive element in addition to providing physical separation also enhances electrical separation between fetal and maternal sensing elements of the fetal probe. Non-invasive fetal probes having low-profile designs are also provided which help decrease the tendency of the fetal probes to detach caused by forces generated upon the probe by the head of the fetus, the cervix of the mother, or both.
