Blood donations save lives. But it does happen that donations become mixed up en route from the donor to the recipient, or the blood deteriorates because it has not been sufficiently cooled – things which are very difficult to verify before a transfusion takes place.

A consortium led by Siemens, in conjunction with the Medical University in Graz, Austria, has developed an RFID system with temperature sensors. continue reading »
