Presentation Summary

  • There are compelling reasons to use energy harvesting technology to displace conventional batteries and/or eliminate the need for wiring
  • Replacing batteries in large wireless networked systems can be inconvenient to replace and unreliable in certain conditions
  • A new proof-of-concept reference design addresses wireless sensor node challenges by measuring temperature, light and charge levels while sending data via a wireless USB dongle
  • Featured technologies include an ultra-low power Wireless MCU and wireless RF ICs from Silicon Labs, power management system from Linear Technology, micro-energy cell from IPS and a solar panel for harvesting energy
