Description
Changde He leads a twelve-author team building an ultrasound kit that finds and sizes bubbles inside silicone sealing rings, in a 2026 study. Hidden bubbles weaken seals, yet the standard X-ray check is bulky, slow, and a radiation hazard. Their pocket system uses two tiny chip-based ultrasound arrays, each under nine millimetres square, with matched sending and receiving electronics.
Sound travel time gives the silicone thickness. How much the returning signal fades, checked against how similar it stays to a reference, reveals bubble size. Tests on factory-grade silicone, backed by computer simulation, reached a spatial resolution of half a millimetre and tracked bubble-driven signal loss well. He's team frames the kit as safer and more portable than X-ray inspection, suited to live checks on the factory floor and faster quality control in seal production.
