- Diffraction and Wireless Charging
When a power beam ‘diverges’ (becomes wider), the distance of the transmitter from the receiver impacts the power capture ability. Let’s discuss the topics of ‘contained beams’ and the impact of diffraction on various power delivery methods.
- Why RF wireless charging might be a good fit for Electronic Shelf Labels
The other day, I read about a company making electronic shelf labels (sometimes also called digital price tags) that is prototyping the use of RF-based charging to deliver energy to these labels. Let’s analyze this in some detail.
- A framework for matching wireless power requirements to available technologies
There is a lot of interest in wireless charging as the next “cutting the power cord” revolution in consumer electronics. A new framework explains the important attributes for a wireless power solution and discusses the performance limits of both infrared and RF technologies.
- Which wireless power technology can charge a phone in your pocket?
The holy grail of wireless charging is charging a phone. Which wireless power technology can charge a phone in your pocket?
- Is it safe?
Blog: When we speak to prospective customers, at some point or another we are asked “is the Wi-Charge technology safe?”.
The short answer is: YES, it is. But let’s dive a bit deeper.
