Wireless Electricity in Smart Cities: Powering Infrastructure Without Cables Smart cities promise cleaner streets, smoother transport and more responsive public services. Behind that vision sits a simple reality: everything in a smart city needs power. Sensors, cameras, displays, traffic systems, meters and communication nodes all depend on a steady energy [...]

Energy Harvesting vs. Wireless Electricity: What’s the Difference? Wireless electricity and energy harvesting often appear in the same conversations, especially when discussing sensors, IoT devices and low-power electronics. While they can work together, they are not the same thing. One delivers energy intentionally from a source. The other collects energy [...]

Ultrasonic Wireless Power: How Sound Waves Can Deliver Electricity Most wireless electricity systems rely on magnetic fields, radio waves or light. Ultrasonic power takes a different path entirely. Instead of using part of the electromagnetic spectrum, it uses mechanical vibrations — sound waves at frequencies far above human hearing. These [...]

How Magnetic Resonance Wireless Charging Works Magnetic resonance is one of the most practical and widely researched approaches to wireless electricity. Unlike long-range concepts that rely on lasers or radio, magnetic resonance focuses on efficient, short-to-mid-range energy transfer using well-controlled electromagnetic fields. It’s the method behind many modern wireless charging [...]

Laser-Based Wireless Power: How Energy Moves Through Light Using light to deliver electricity sounds like something out of a science fiction film, yet it’s one of the most practical forms of wireless power being developed today. The idea is simple at the surface: convert electricity into a controlled beam of [...]

RF Wireless Charging: How Radio Waves Deliver Power Through the Air Most people are familiar with radio waves as a way to send information — phone calls, Wi-Fi signals, Bluetooth connections, broadcast radio. But radio waves can carry something else too: energy. That idea is the foundation of RF wireless [...]
