1. A sensor system comprising:
- a laminate base comprising a plurality of laminated layers including at least a top layer having a top surface, a bottom layer having a bottom surface, and at least one internal layer laminated between the top layer and the bottom layer, the laminate base having a side surface extending between the top surface the bottom surface, the top surface, bottom surface and side surface comprising an external surface of the laminate base;
a first sensor in an internal layer, such that the first sensor is laminated between two of the plurality of laminated layers;
a second sensor in an internal layer, such that the second sensor is laminated between two of the plurality of laminated layers; and
an aperture extending through the external surface and from the external surface through at least a portion of the laminate base so as to expose the first sensor to an external environment.

Abstract
Backside recesses in a base member host components, such as sensors or circuits, to allow closer proximity and efficient use of the surface space and internal volume of the base member. Recesses may include covers, caps, filters and lenses, and may be in communication with circuits on the frontside of the base member, or with circuits on an active backside cap. An array of recessed components may a form complete, compact sensor system.
