sensors._x000D_
Wavelite addressees this problem by leveraging back-scattering concepts in wireless communications._x000D_
Wavelite makes backscatter communication possible using conventional WiFi devices in which the carrier_x000D_
wave is recycled from WiFi signals of an existing WiFi device such that another conventional WiFi device_x000D_
receives the backscattered signal. Wavelite technology intends to reduce the practical power consumption of_x000D_
the sensor's communication component node in a range between hundreds of micro-Watts to a few milli-Watts_x000D_
to enable the use of micro power harvesting solutions. To achieve this goal, various innovative hardware_x000D_
implementations of WiFi backscattering systems must be explored. As part of this project, we intend to 1)_x000D_
investigate various methodologies to reduce the power consumption of existing low power backscattering_x000D_
nodes, and 2) explore power harvesting techniques that are suitable for the backscatter technology. Based on_x000D_
simulations and analysis, several solutions pertaining to low-power off-the-shelf components, ASIC or_x000D_
re-configuration of the digital system to achieve these goals will be explored. In addition, several harvesting_x000D_
techniques will be tested and adapted to the required low-power context., program purpose french : Power consumption of wireless sensor nodes is a key limiting factor towards battery-free operation of these_x000D_
