1. A surgical reference system, comprising:
- a substrate that conforms to and moves with an internal organ or internal tissue when placed thereon;
three or more sensor elements each generating x, y, and z coordinate information and integrated on the substrate, wherein the sensor elements generate one or both of positional or directional signals when in use; and
a power supply electrically connected to the three or more sensor elements.

Abstract
A substrate configured for placement on an internal organ or internal tissue is provided. In certain embodiments, the substrate conforms to and moves with the internal organ or internal tissue. Three or more sensor elements are integrated on the substrate. In one implementation, the substrate and associated sensor elements provide dynamic referencing of the internal organ or internal tissue after registration of the sensor data with images and/or volumetric representations of the internal organ or internal tissue.
