#MEMS: "Blast Gauge Monitors Soldier's Concussions"

When an improvised explosive device (IED) or mortar round explodes near a soldier often they are too disoriented afterwards to even know whether they should seek medical help, but by wearing a Blast Gauge soldiers in Afghanistan can find out immediately. After a nearby explosion, the soldier merely pushes a button on the Blast Gauges and it either lights green (OK), yellow (border line) or red (seek medical attention immediately): R. Colin Johnson



Here is what EETimes says about the Blast Gauge: Ultralow-power accelerometers, which draw only nanoamps while holding idle electronics in zero-consumption standby mode, can extend the battery life of freestanding sensors for up to a decade. Analog Devices Inc. says its newest three-axis accelerometer can extend battery life for months even in always-on devices. The part is being tested for use in the Blast Gauge, which the Defense Department has deployed to monitor soldiers 24/7 for exposure to the concussive forces of munitions...
