Abstract: A method for biometric identification includes: acquiring a first fingerprint image by using a first image capturing mode, where the first fingerprint image is used for first biometric identification, and the first biometric identification includes fingerprint identification; and acquiring a plurality of frames of second fingerprint images by using a second image capturing mode, where the plurality of frames of second fingerprint images are used for second biometric identification, and the second biometric identification includes at least one of heart rate detection, blood oxygen detection or living body detection, and the first image capturing mode is different from the second image capturing mode. The method for biometric identification is beneficial to improve detection performance.

Abstract: A method of forming a metal oxide material having a rod shape or polyhedral nanostructure includes preparing a first reverse micro-emulsion system comprising an aqueous precipitating agent dispersion and a second reverse micro-emulsion system containing an aqueous metal salt dispersion; combining the micro-emulsions together to initiate a reaction; allowing the reaction to continue to form a product mixture comprising a metal oxide gel and aqueous media; separating the metal oxide gel from the aqueous media; collecting the metal oxide gel; and calcining the metal oxide gel to form the metal oxide material. The metal oxide material corresponds to the chemical formula of La2MxNi1-xO4, Pr2-yAyNiO4, or La2-zDzNiO4, wherein M is copper, cobalt, iron, manganese, chromium, aluminum, or platinum; A is lanthanum or neodymium; D is calcium, barium or strontium; x ranges from 0 to 1; y ranges from 0 to 2; and z ranges from 0 to 0.25.

Abstract: The present disclosure provides an optical fingerprint identification apparatus and an electronic device. The apparatus includes a fingerprint identification module disposed under a backlight module of the liquid crystal display. The fingerprint identification module includes an optical sensor and a light source disposed adjacent to the optical sensor; the light source is used to emit a detection light to the fingerprint detection area of the liquid crystal display, and the detection light passes through the liquid crystal display via a transmission part of the backlight module and irradiates to a finger above the liquid crystal display to form a fingerprint detection light carrying fingerprint information; and the optical sensor is used to receive the fingerprint detection light to acquire the fingerprint information; where the fingerprint detection light passes through the liquid crystal display and is transmitted to the optical sensor via the transmission part of the backlight module.
