With the help of wireless sensors, Stanford researchers confirmed what most of us suspected. When it comes to infectious viruses, human beings are toast. The researchers outfitted an entire high school population with IEEE 802.15.4 sensors for one day to model what they call a "human contact network." The devices tracked how often people came within the infection-spreading range of other individuals during a typical height-of-flu-season January day. Every teacher, student and staff member at the school carried a credit card-size TelosB device that sent and received signals every 20 seconds. The TelosB mote is a low-power programmable wireless sensor module specifically geared for research projects... Read more...
