PRESSURE SENSITIVE MICROPARTICLES FOR MEASURING CHARACTERISTICS OF FLUID FLOW

摘要

Microparticles (200) and systems and methods for measuring characteristics of fluid flow using the microparticles are described. The microparticle (200) can include at least one flexible wall (205) which can deflect when an outer pressure on an outer side of the wall is different than an inner pressure on an inner side of the wall. The microparticle (200) can also include a void (215) enclosed by the at least one wall (205) and can change shape as the wall (205) deflects.
