Oppo envisions a future where battery-free devices are powered by ambient radio waves

There may be many ways in which we may utilize Zero-Power technology. According to Oppo, Zero-Power technology may be used in wearables, thus enabling them to be powered passively. Zero-Power Communication devices may also be used in transportation, as smart home devices, as location tags, and even in the long-distance tracking of migratory birds.

Oppo’s vision of a battery-free future for low-power IoT (Internet of Things) devices is shared in a new white paper (via Android Authority). According to Oppo, in the future, instead of a built-in battery, we may utilise devices that take power straight from Bluetooth, Wi-Fi, and cell phone signals. These are what Oppo refers to as “Zero-Power Communication” devices. Zero-Power Communication devices, according to Oppo, are “battery-free, highly small, ultra-low-cost, and may have ultra-low power consumption.” Zero-Power Communication devices could reduce the consumption of batteries in general, cutting the expenses of maintenance and pollution that we currently encounter with current gadgets.

Oppo’s vision of using devices powered over the air is not something new. Devices using similar technology have been previously demonstrated by Samsung, Xiaomi, and Motorola. At CES 2022, Samsung announced its latest Eco Remote, which harvests 2.4GHz Wi-Fi signals from its surroundings to power itself, thus eliminating the need for batteries.

Although Oppo is talking about passively powering devices, its Zero-Power technology may not be able to deliver the power needed to charge phones. Oppo’s technology also differs from what Xiaomi and Motorola have introduced and called “air charging” technology, which can charge phones from a distance using a dedicated station emitting targeted, low-level radio frequency waves.
