Roland Piquepaille writes "After a patient has been hospitalized for a surgical intervention, he usually wants to return to his normal life. But doctors would like to monitor him to be sure that the operation was successful. How can they manage this without being too intrusive? In "Health Care Monitoring of Mobile Patients," Italian researchers offer a three-layer networking solution. First, a body area sensor network would continuously record your cardiac activity or your body temperature. A second level would involve a home sensor network, including for example a PC wirelessly receiving this information. Finally, this home network would be able to alert an hospital network if needed. Right now, this whole idea is at the proof-of-concept level, but it really looks promising."
