  • Publication number: 20220306877
    Abstract: Methods of fabricating 3D printed structures from biocompatible proteins include forming a photoreactive, proteinaceous resin, and 3D printing biocompatible structures from the resin by the patterned application of light in a select wavelength to cure the resin into the desired structures. Suitable photoreactive proteinaceous resins can be formed by reacting an aqueous solution of an acrylated or methacrylated globular protein with a photoreactive comonomer or photoinitiator. Structures printed from the photoreactive, proteinaceous resin can be photo-cured and dried to form bioplastic structures.

  • Patent number: 11413007
    Abstract: Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.
