Abstract

Aspects of the present disclosure include a sensor emitter including a reflective cavity for re-directing light to a tissue site. By reflecting light towards the tissue site, the amount of light reaching the tissue site is increased. The increased light can improve parameter measurements taken by a non-invasive physiological sensor by producing a stronger and/or cleaner signal. In an embodiment, the reflective cavity is formed on one or more lead frames of the sensor emitter, wherein the lead frames are capable of transmitting electrical signals to emitting elements coupled to the lead frames. Aspects of the present disclosure also include a sensor component configured to protect connection points of wires to conductive leads on the sensor components by inhibiting flex or bending at the connection points. Connection points can protrude along edges of the sensor component. Aspects of the present disclosure also include techniques and processes for producing low-profile sensors.
