Electronic identification of cryobiological specimens is an emerging technology in the field of advanced biological specimen banking. In this paper, we focus on the design and evaluation of a radio-frequency identification transponder (RFID) using a low-frequency carrier signal for wireless specimen identification between room temperature and liquid-nitrogen temperatures. The transponder design is based on a commercial-off-the-shelf CMOS integrated circuit. The chip contains 1 kbit of EEPROM for user-defined data storage. We describe the design technique and results for the component and transponder characteristics at room temperature and 77 K. We have assembled a batch of prototype devices and tested them down to liquid-nitrogen temperature to verify the transponder design and present test results for read and write operations. We suggest further development steps including miniaturization, packaging and extended functionality.
