With a total of 2 patents, Cheng's work focuses on innovative solutions that enhance the capabilities of tissue engineering and material fabrication.

Latest Patents

Cheng's latest patents include a groundbreaking tissue printer. This bioprinter enables the in situ formation of architected planar biomaterials and tissues by translating a printer head along a deposition surface, such as skin wounds. In handheld configurations, cell-laden biopolymer solutions are perfused through a moving microfabricated printhead and deposited onto a stationary planar surface or a wound. The printer head may be translated via a drive mechanism, allowing for versatile applications. Different embodiments of the instrument are disclosed for in vivo application in small animals, as well as for large animal and clinical applications. Additionally, a stationary embodiment of the instrument is well suited for the continuous formation and roll-to-roll processing of planar biomaterials and tissues.

Another notable patent involves fluidic systems, devices, and methods for inducing anisotropy in polymeric materials. This invention provides systems and methods for fabricating anisotropic polymer materials. A fluidic device is employed to distribute a polymer solution and a flow-confining solution to generate a layered flow. The layered flow is formed such that a polymer liquid sheet is sheathed on opposing sides by flow-confining liquid sheets. The fluidic device includes first and second fluid conduits, where the first fluid conduit receives the layered flow. The second fluid conduit has a reduced height relative to the first fluid conduit, causing hydrodynamic focusing and inducing molecular alignment and anisotropy within the polymer liquid sheet.
