Wireless powered electrochromic windows
Electrochromic windows powered by wireless power transmission are described, particularly, the combination of low-defectivity, highly-reliable solid state electrochromic windows with wireless power transmission. Wireless power transmission networks which incorporate electrochromic windows are described.
1. A wireless power transmission network, comprising:
a plurality of windows in an area, wherein the windows are in electrical communication; and
a wireless power transmitter comprising a radio frequency antenna configured for wireless power transmission to one or more devices in the area,
wherein each of the windows is in the form of an insulated glass unit having a spacer and a seal between two panes and the spacer.
2. The wireless power transmission network of claim 1 , wherein the area is within a building.
3. The wireless power transmission network of claim 1 , wherein the radio frequency antenna is located outside the area.
4. The wireless power transmission network of claim 1 , wherein the one or more devices comprises an electrochromic device.
5. The wireless power transmission network of claim 4 , wherein the electrochromic device is solid state and inorganic.
6. The wireless power transmission network of claim 4 , wherein the wireless power transmission is used to power transition of tint of the electrochromic device.
7. The wireless power transmission network of claim 1 , wherein transmission of wireless power is localized to the area.
8. The wireless power transmission network of claim 1 , wherein the radio frequency antenna is located in or on a frame of the insulated glass unit of one of the windows.
9. The wireless power transmission network of claim 1 , wherein the radio frequency antenna is housed in the seal of the insulated glass unit of one of the windows.
10. The wireless power transmission network of claim 1 , wherein the radio frequency antenna or the wireless power transmitter is part of a window controller.
11. The wireless power transmission network of claim 1 , wherein the wireless power transmission is configured to charge a battery.
12. The wireless power transmission network of claim 1 , wherein the one or more devices comprises a motion sensor, a light sensor, a heat sensor, a moisture sensor, or a wireless communication sensor.
13. The wireless power transmission network of claim 1 , further comprising a receiver configured to relay the wireless power transmission to the one or more devices.
14. The wireless power transmission network of claim 1 , wherein the wireless power transmission comprises one or more different levels or types of power configured for power requirements of the one or more devices.
