Yes, it is amazing, Chuck. I remember Moore's Law getting called dead 15 years ago. It seems as though the laws of physics have been bent to the will of Moore's Law. I believe that at some point there will be a leap in EV technology. But so far, it's been stubburn.

Yes, Rob, it's amazing what Moore's Law can do.

Yes, that's quite an improvement. Much different from the EV that goes from 35 miles to 38 miles before a charge.

Halo Monitoring company in Huntsville, Al is working on a fall, detection system for the elderly. Although batteries are not required,, the ADXL326 can be used to determine! the position cart of an elevator as well.

I see this as being a part of a low cost, low power elderly monitoring system as mentioned in the article.  The idea of livestock monitoring in the long term is also very feasible and quite useful.

The trend for semiconductor manufacturers is to develop electronic products that assist in reducing power consumption to converse batteries which is the primary source for today's consumer and medical products. Analog Devices is one of the leaders in low power semiconductor technology as illustrrated in their new wireless MEMs based accelerometer (ADXL362) product.

Good point, Rob. Sixty percent is a bigger improvement than you'll typically see in any kind of new product. This kind of low power draw should be popular in energy harvesting applications.

The low power aspect of the sensor seems significant at a 60 percent reduction in required electrical current. It's also good to see component manufacturers competing on low power.
