Summary:
- This article discusses a new type of smartphone that does not require a battery. Instead, it uses a technology called "backscatter" to power the device.
- Backscatter technology allows the smartphone to communicate with a nearby device, like a router, and use the energy from the radio waves to power its components.
- This means the smartphone can operate without a traditional battery, making it more energy-efficient and potentially longer-lasting than current smartphone models.
