Abstract: Disclosed is a method for manufacturing a secondary battery, including a first charging step to SOC 10% or less and a high-temperature aging step in the battery activation step. In the method for manufacturing a secondary battery, gases generated after the first charging step are removed through the subsequent high-temperature aging step, and thus the electrode shows improved charging uniformity in the subsequent charging step, and the battery shows increased available capacity.

Abstract: The present disclosure relates to a microelectrode for measuring EMG signals of a laboratory microfauna. The present disclosure includes a metal plate with an insulating plate deposited on a surface, a plurality of silicon substrates disposed on the insulating plate, the silicon substrates being electrically connected to the metal plate, covered with an insulator, and adjacent to one another, and a plurality of needle electrodes, each formed on the respective silicon substrates as an integral part thereof, wherein the needle electrodes have the same predetermined length, have a tapered shape from the respective silicon substrates, are spaced apart from each other by a predetermined distance, and wherein a metallic layer is formed on each of the needle electrodes by depositing metal materials, the insulator is formed on the metallic layer, and a portion of the metallic layer at a tip is exposed.

Abstract: Disclosed herein is an optical stimulator inserted into a biological tissue for obtaining a neural signal by stimulating a neuron with a propagating light. The optical stimulator includes: a main unit comprising electrodes, and electrical terminals connected to the electrodes; a waveguide extended from a side of the main unit and comprising electrochromic films; and a light source disposed in the main unit and producing light along a direction in which the electrochromic films formed in the waveguide are arranged. Each of the electrical terminals is connected to the respective electrochromic films, and the electrochromic films change a propagation path of light reaching the electrochromic films upon a voltage being applied thereto from the electrical terminals, to stimulate a neuron.
