Application: Digital light processing 3d printed monolithic substrates with integrated and embedded sensors (Patent ID: US20240140022A1)
The patent filed by Toyota Motor Corp. describes a sensor with a grayscale digital light processing (g-DLP) 3D printed monolithic substrate containing microfluid channels for sensor fluid. The substrate is made from a resin that forms a solid polymer using g-DLP 3D printing, with a Young's modulus ranging from 0.1 MPa to 100 MPa. The resin composition includes donor and acceptor moieties in the form of acrylate monomers, a rigid moiety, a photoinitiator, and a photoabsorber.
The sensor claims detail the specific composition of the resin, including the donor moiety as 2-hydroxyethyl acrylate, the acceptor moiety as aliphatic urethane-based diacrylate, and the rigid moiety as isobornyl acrylate. The sensor fluid within the microfluid channels can be electrically resistive. The patent also mentions the Young's modulus distribution within the substrate and the weight percentage ranges of the resin components. Overall, the sensor design aims to provide a durable and efficient sensing solution with precise control over material properties and fluid interactions.
