Le déanaí d'fhorbair taighdeoirí aeróg nua bunaithe ar mheiteashonraí, rud a léiríonn céim mhór i dtreo an sprioc maidir le fuinneamh a bhaint as tonnta raidió. Leis an teicneolaíocht seo, is féidir le húsáideoirí cumhacht gan sreang a sholáthar do bhraiteoirí, do LEDanna, agus do ghléasanna simplí eile a bhfuil riachtanais ísealfhuinnimh acu trí na tonnta raidió a úsáideann Wi-Fi, tarchur Bluetooth, srl.
"By eliminating wired connections and batteries, these antennas can help reduce costs, improve reliability, and make some electrical systems more efficient," said research team leader Jiangfeng Zhou from the University of South Florida. "This will help Powering smart home sensors, such as those for temperature, lighting, and motion, or for monitoring the structure of buildings or bridges, where changing batteries may be difficult or impossible."
Foilsíodh na torthaí taighde le déanaí in Optical Materials Express.
Tuairiscíonn na taighdeoirí go léiríonn tástálacha saotharlainne ar a n-aeróg nua gur féidir leis 100 micreawatt cumhachta a bhaint as tonnta raidió ísealchumhachta, go leor chun gléas simplí a chumhachtú. Tá sé seo indéanta toisc go léiríonn an meite-ábhar a úsáidtear chun an t-antenna a dhéanamh ionsú foirfe tonnta raidió agus go bhfuil sé deartha chun oibriú ar dhéine íseal.
"While more work is needed to miniaturize the antenna, our device uses ambient power levels found in the real world at high The efficiency crosses the critical threshold of 100 microwatts of harvested power. The technology can also be tuned so that it can provide a source of radio waves to power or charge devices around the room."
Tá eolaithe ag iarraidh fuinneamh a bhaint as tonnta raidió le tamall maith anuas, ach bhí deacrachtaí acu dóthain fuinnimh a fháil chun feidhmiú. Tá athrú ag teacht ar an scéal seo, a bhuíochas le forbairt na meite-ábhair agus na-foinsí comhthimpeallacha atá ar fáil de shíor ag méadú, mar líonraí fón póca, Wi-Fi, comharthaí GPS agus Bluetooth.
Zhou said: "With the huge explosion of radio wave-based technologies, there will be a large amount of waste electromagnetic radiation that can be collected. This, coupled with advances in metamaterials, creates a ripe environment for new devices and applications, These devices and applications can benefit from capturing this waste energy and putting it to use."
