Metamaterial and NFC based pad charges multiple devices wirelessly

Oxford-incubated and fund-looking UK based startup Metaboards has developed a wireless charging platform called Evenlode. Evenlode can charge multiple hearable and wearable devices at the same time, wherever they are placed on its surface. Users just need to put the device over the wireless charging board without bothering about specific position or alignment. The wireless charger system finds these devices and charge them without wasting excessive power. Metaboards has made a video demonstration of how it works. The video is available at https://vimeo.com/651187694 This is something new compared to present wireless chargers where the present chargers can only charge a single device at a time and most of them require the user to place the device in a specific position. Having a size of a tablet computer, this new charging platform uses metamaterials and a smart software algorithm, where the charging surface locate and charge up multiple devices wherever they are placed. This board is said to take benefit of an update of Near Field Communication (NFC) standard that widens NFC’s remit by adding charging to its widely-used functions of making payments and granting access. Key features of NFC wireless charging: Charging at 13.56MHz Power from 100mW to 1W Supporting small consumer & IoT devices Easy integration with tiny antenna footprints Leveraging existing NF...
