Bluechiip Cryogenic Delta Tag

The Bluechiip Cryogenic Delta Tag is a highly miniaturised passive identification device for wireless tracking and management of high-value biological samples in cold storage medical applications. The tag also features instantaneous measurement of the tag’s temperature.

The tag is immune to extreme environments such as gamma radiation and storage and operation in cryogenic environments, making it suitable for biobank applications. It is designed for use in conjunction with the Bluechiip Matchbox Reader and the Bluechiip Stream sample and inventory management software.

Each tag is made of a MEMS-based microchip mounted on a printed circuit board antenna. The microchip contains Lorentz force resonators tuned to frequencies between 1.3 and 4.1 MHz. The device is passive, in that it does not require power but obtains its energy via a read signal from the Matchbox Reader. The resonators in the chip are stimulated via the antenna by the Matchbox Reader and subsequently return a signal indicating the unique identifier and temperature of the tag. Each chip is programmed during the manufacturing process with a unique identification number and every read of the tag is checked by an internal BCH error detection and correction code.

The tags are suitable for application in biobanks, bio-repositories and cryopreservation facilities; cryogenic stored samples; stem cell storage; clinical trials; cell lines; in vitro fertilisation (IVF); general laboratory use; pharmaceuticals; and blood products.
