  • Patent number: 11677353
    Abstract: A variable capacitor circuit includes a capacitor block including a first varactor element comprising a first transistor having a first size, a second varactor element comprising a second transistor having a second size different from the first size, a first terminal commonly connected to a source and a drain of the first transistor, a second terminal commonly connected to a source and a drain of the second transistor, and an RC circuit connected to a gate of the first transistor and a gate of the second transistor.
    Type: Grant

  • Patent number: 11581518
    Abstract: Disclosed are a probe integrated with an organic light source and a manufacturing method thereof. An organic light source integration method includes forming a first thin film encapsulation layer on a probe shank, depositing a first electrode in a first region on the first thin film encapsulation layer, depositing an insulating layer in a second region on the first thin film encapsulation layer, depositing a light emitting layer on the first electrode and the insulating layer, depositing a second electrode on the light emitting layer, and forming a second thin film encapsulation layer on the second electrode.

  • Publication number: 20220297117
    Abstract: Disclosed is a blood-brain barrier vascular network implemented in a microfluidic chip. The blood-brain bather vascular network structure (BBB on a chip) (in vitro blood-brain bather (BBB)-on-a chip) formed in a microfluidic chip manufactured by a present manufacturing method of the in vitro blood-brain barrier (BBB)-on-a chip may reconstruct the blood-brain barrier in a real human body more similarly due to a specific cell configuration, compared to the conventional in vitro blood-brain barrier (BBB)-on-a chip, and thus may be used as a more accurate in vitro blood-brain barrier, and may be used for the development of various cellular therapeutic agents or drugs that work in the treatment of various brain diseases.
