Email: Is energy harvesting for WSNs overhyped?
3/12/2010 11:32 AM EST
Here are two quesitons for your panel on wireless sensor networks (see ESC: Panel to debate wireless sensor networks).
You probably have these questions on your agenda but just in case.
What is the impact of a standard such as ZigBee RF4CE on industrial wireless sensor networks as well as home/consumer networks? Will ZigBee RF4CE speed adoption of this new technology?
What is the future of energy scavenging and/or energy harvesting for wireless sensor networks. Is a better answer the adoption of ultra-low power wireless like ZigBee Green Power which relies on inexpensive long lived batteries (ten years or more) as compared to expensive energy harvesting technologies? Is a low-tech approach more effective? Reduce the power required by the WSN so that it can operate on a single battery for the life of the system.
In other words is energy harvesting over-hyped?

The current power reduction trend will continue as will the advances in battery tech. These combined efforts will soon eclipse product lifetime.
The energy harvesting window is closing faster than the technology is advancing. Once this tech arrives it may only find niche applications.
