# How a Device Receives Wireless Power Using Terahertz Waves and Blockchain > This patent describes a receiver device that wirelessly collects terahertz electromagnetic energy using special materials and an antenna, then converts it to electricity, but only after a transmitter authenticates it using a blockchain. - **Patent:** US 11171521 - **Original title:** Receiver device for facilitating wireless energy reception - **Owner:** Voice Life - **Granted:** 2021 - **Status:** Active - **Times cited:** 0 - **Field:** consumer_electronics, telecommunications, software, materials, semiconductors, energy ## What it does The patent describes a receiver device designed to get power without wires. It uses a special "receiver transceiver" (Claim 1) that has an outer casing, called a "receiver enclosure," made with "metamaterial" (Claim 1). This enclosure is designed to catch and store "terahertz electromagnetic wave energy" (Claim 1) and turn it into regular electricity that can power other gadgets. The device's antenna, which helps it grab this energy, is made with "superconducting material" (Claim 1) for better efficiency. Before any power is sent, the receiver sends a "registration request" with a unique ID to a transmitter (Claim 1). The transmitter then checks this request against a "distributed block-chain" (Claim 1) to make sure the receiver is allowed to get power, and only then does it send the terahertz energy. For example, a smartphone with this receiver could request power from a nearby transmitter, which would verify the phone's identity on a blockchain before wirelessly charging it. ## What it does NOT cover - Does not cover wireless power transfer using frequency ranges other than terahertz electromagnetic waves. - Does not cover receiver devices that do not incorporate a metamaterial in their enclosure. - Does not cover receiver antennas that are not made with at least one superconducting material. - Does not cover wireless energy systems where the transmitter does not authenticate the receiver using a distributed blockchain. - Does not cover energy conversion systems that do not specifically store terahertz energy before converting it to electrical energy. - Does not cover wireless power systems that rely solely on near-field inductive or resonant coupling. ## The clever bit The novelty lies in the specific combination of a receiver enclosure using metamaterials to efficiently capture and store terahertz electromagnetic energy, an antenna made of superconducting material for high efficiency, and a blockchain-based authentication system to ensure only authorized devices receive power. This creates a secure and highly efficient wireless power ecosystem. ## Real-world examples 1. Future long-range wireless charging systems for consumer electronics 2. Internet of Things (IoT) devices powered remotely 3. Smart home devices receiving continuous power 4. Medical implants charged without physical contact ## Why it matters This patent outlines a sophisticated approach to wireless power transfer, combining advanced material science with secure digital authentication. While the specific technologies like terahertz power delivery and blockchain authentication are still emerging for consumer wireless charging, this patent lays a foundation for future systems that could offer secure, efficient, and potentially long-range power delivery. The assignee, Voice Life, focuses on wireless power, suggesting a future where devices are continuously powered without physical connections. ## Frequently asked questions ### What does How a Device Receives Wireless Power Using Terahertz Waves and Blockchain cover?
