摘要:
A radio-frequency identification tag for identification of cryo-preserved samples down to cryogenic temperatures, comprising an antenna (2, 3) and an integrated circuit chip (4) designed to be operative at cryogenic temperatures. The antenna is formed by a coil (3) wound around a ferrite core (2). The radio-frequency identification tag is configured to fit within a vessel having a diameter down to 1.4mm. A system for identification of cryo-preserved samples at cryogenic temperatures. A method of tuning a radio-frequency identification tag for identification of a cryo-preserved sample stored in a vessel at cryogenic temperatures.
