RheaWave is a start-up developing ultrasound technology for texture and viscoelasticity Quality Control of finished products or in course of manufacturing. Attractive for Foods and Cosmetic industries, RheaWave proposes a texture on-line sensor, nondestructive and contactless: RheaOnLine, allowing a real time follow-up of the viscoelastic properties of the product (raw materials optimization, manufactured product historic). RheaWave’s activity is based on a patented acoustic technology. This innovative technology is sensitive to the presence of microcracks, microbubbles, microdamages in the matter. Our company proposes studies services dedicated to Non Destructive Testing of materials, in other industrial sectors such as metallurgy, or plastics and rubber manufacturig.
