  • Publication number: 20230088763
    Abstract: The present disclosure describes a new resin which can be fabricated into conductive and bioactive microstructures via two-photon polymerization. The direct incorporation of conductive poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) and/or multi-walled carbon nanotubes (MWCNTs) in a poly(ethylene glycol) diacrylate (PEGDA)-based blend remarkably enhances the electrical conductivity of microstructures over 10 orders of magnitude. Including biomaterials in the resin can promote cellular adhesion and create functional biosensors made of hybrid non-conductive and conductive structures for sensitive detection. Applications include development cost effective microelectronics in a broad range of biomedical research, electronics and sensors.

  • Patent number: 11553839
    Abstract: Provided herein are systems and methods to measure the intraocular pressure, ocular tissue geometry and the biomechanical properties of an ocular tissue, such as an eye-globe or cornea, in one instrument. The system is an optical coherence tomography subsystem and an applanation tonometer subsystem housed as one instrument and interfaced with a computer for at least data processing and image display. The system utilizes an air-puff and a focused micro air-pulse to induce deformation and applanation and displacement in the ocular tissue. Pressure profiles of the air puff with applanation times are utilized to measure intraocular pressure. Temporal profiles of displacement and/or spatio-temporal profiles of a displacement-generated elastic wave are analyzed to calculate biomechanical properties.

  • Publication number: 20220386862
    Abstract: A system and method for measuring biomechanical properties of tissues without external excitation are capable of measuring and quantifying these parameters of tissues in situ and in vivo. The system and method preferably utilize a phase-sensitive optical coherence tomography (OCT) system for measuring the displacement caused by the intrinsic heartbeat. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. Preferably, the method is used to detect tissue stiffness and to evaluate its stiffness due to intrinsic pulsatile motion from the heartbeat. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases and evaluating the efficacy of therapies.

  • Patent number: 11519175
    Abstract: A self-stressing shape memory alloy (SMA)/fiber reinforced polymer (FRP) composite patch is disclosed that can be used to repair cracked steel members or other civil infrastructures. Prestressed carbon FRP (CFRP) patches have emerged as a promising alternative to traditional methods of repair. However, prestressing these patches typically requires heavy and complex fixtures, which is impractical in many applications. This disclosure describes a new approach in which the prestressing force is applied by restraining the shape memory effect of nickel titanium niobium alloy (NiTiNb) SMA wires. The wires are subsequently embedded in an FRP overlay patch. This method overcomes the practical challenges associated with conventional prestressing.
