Wireless Sensors A new device developed by Stanford University researchers could make it easier for doctors to monitor the success of blood vessel surgery. The sensor, detailed in a paper published Jan. 8 in Nature Biomedical Engineering, monitors the flow of blood through an artery. It is biodegradable, battery-free and wireless, so it is compact and doesn't need to be removed and it can warn a patient's doctor if there is a blockage.

New Technology for the Blood Service In a world-first study, the Australian Red Cross Blood service is conducting research into the use of leading-edge technology to visualise blood donors’ veins during blood donation. The vein visualisation devices are portable, and project an image of the veins onto the skin’s surface using non-invasive near infra-red technology. The Blood Service is aiming to find out if this procedure reduces anxiety, improves donation comfort and makes donors more likely to donate again. The study will assess the responses of 300 first-time and 600 return donors aged between 18 and 30 attending the Chatswood and Elizabeth Street Donor Centres in Sydney. "Donor Centre staff have found the technology particularly useful in cases where the vein is not visible to the naked eye” said Dr Dan Waller, one of the senior investigators on the trial. “We are keen to retain our young donors, and it is important to test if this technology may help us do that.” The results of the research so far will be presented at a conference in Philadelphia in late October
