<unk>  <unk>  is a gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors. For a<unk>  system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most 1 cm apart. Two dominant pressure transduction technologies are used: solid state pressure sensors and water perfused pressure sensors. Each pressure transduction technology has its own inherent advantages and disadvantages.<unk>  systems also require advanced computer hardware and software to store and analyze the<unk>  data.
