1. A method for determining a direction of flow through a gastrointestinal tract, the method comprising:
- inserting first and second pH sensors within the gastrointestinal tract, the first and second pH sensors separated by a distance D;
sampling an output of the first and second pH sensors over time;
determining a gradient between the output of the first and second pH sensors over time; and
determining the direction of flow over the distance D based on the gradient.

Abstract
A device, system and method for in-vivo sensing (e.g., pH sensing, pressure sensing, or other sensing) may include more than one sensor receiving in-vivo data. The sensed data may be analyzed to, for example, determine a gradient or fluid flow. A device including multiple sensors may be held or immobilized in-vivo, and may detect a fluid flow or gradient moving past the sensors.
