using a series of closely spaced pressure sensor
Pressure sensor
A pressure sensor measures pressure, typically of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the...

Manometry
Manometry refers to the evaluation of pressure .Forms include:* Esophageal motility study* Anorectal manometry* Rhinomanometry...
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, (i) solid state pressure sensors, and (ii) water perfused pressure sensors. Each pressure transduction technology has its own inherent advantages and disadvantages. HRM systems also require advanced computer hardware
Computer hardware
Personal computer hardware are component devices which are typically installed into or peripheral to a computer case to create a personal computer upon which system software is installed including a firmware interface such as a BIOS and an operating system which supports application software that...
and software to store and analyze the manometry data.
