Batteries FOR LIFE

摘要

The world is going wireless. Currently, there are approximately 80 million wireless-monitoring systems in use worldwide, serving applications ranging from building automation to vibration-monitoring systems and mesh networks. Oak Ridge National Laboratory recently outlined 12 top requirements for an ideal wireless sensor. Researchers there concluded that the number-one criterion was the need for an adequate battery life, followed by the need to be self-powered and small. This study makes clear how important battery technology is for practical wireless sensors.
