  • Publication number: 20250134433
    Abstract: The present disclosure relates to a flexible electrode and a manufacturing method therefor. Provided is a flexible electrode, comprising at least one implantable and flexible electrode wire and a continuous limiting layer. Each electrode wire comprises: a wire, the wire being located between a first insulating layer and a second insulating layer of the flexible electrode, and an electrode site, the electrode site being in contact with the biological tissue after implantation of the electrode wire, being located on the first insulating layer, and being electrically coupled to the wire by means of a through hole in the first insulating layer. The limiting layer is located on the at least one electrode wire and is configured to be detachably adhered to the at least one electrode wire, so that the at least one electrode wire is kept in a fixed arrangement during the implantation process.

  • Patent number: 10359414
    Abstract: Devices and methods for performing frequency domain (FD) fluorescence lifetime spectroscopy are provided. The devices include a modulated light source, a focusing optical fiber, a detecting optical fiber, and a detector. The methods include focusing sinusoidal modulated incident light from a light source on a biological sample containing a protein, detecting a range of wavelengths of sinusoidal modulated fluorescent light emitted from the protein, determining a phase shift for the modulated fluorescent light, determining an amplitude modulation of the modulated fluorescent light, and determining a fluorescence lifetime of the protein.
