Title: The Innovations of Francis Hai
Introduction
Francis Hai is an accomplished inventor based in Torrance, California. He has made significant contributions to the field of stress sensing technology, holding a total of 2 patents. His work focuses on innovative materials and methods that enhance the performance of stress sensors.
Latest Patents
One of Francis Hai's latest patents is a microballoon impregnated fiber reinforced RTV film compression stress sensor. This thin film sensor is designed to measure the maximum compressive stress between two elements that are compressed together. The sensor is formed from a thin RTV film that is impregnated with microballoons and reinforced with carbon fibers. This reinforcement helps to restrain the lateral deformation of the RTV, allowing for more uniform pressure to be exerted on the microballoons during uniaxial compression. The testing method involves applying compressive stress to rupture a first portion of the microballoons, followed by an interrogating pressure that causes acoustic emissions from a second portion of the microballoons. This process helps determine the maximum compressive stress accurately.
