Here’s how. You’d be forgiven if you assumed the Internet of Things (IoT) was just about communication. All those smart devices, smart buildings, appliances, cars, etc. communicating wirelessly all the time. But that’s the Internet of Expensive Things, which includes about 11 billion connected devices, by some estimates. The Internet of Everyday Things will likely be a hundred times bigger—an Internet of Trillions. This IoT is all about by power: capturing and recycling the necessary power to communicate wirelessly anywhere at any time. In this Internet of Trillions, packaged goods will communicate their location and condition; clothes communicate their origin and sustainability journey; and vaccines communicate information about their handling and viability. Similarly, a reusable transport item—a plastic pallet or a crate—becomes a remarkable data store, sensing its surroundings and communicating, for example, whether a shipment of fresh vegetables has been kept at a safe temperature and transported quickly enough to maintain freshness. But how, when none of these everyday things is plugged into or powered by a traditional battery, can they communicate wirelessly via the internet? After all, everyone with a smartphone knows it takes battery power (and often, a backup charger). Using innovative new technology, everyday things can communicate wirelessly by actually creating their own power. They do so by harvesting the wireless energy that’s all around us The Best Energy Harvester is a Sophisticated Scavenger Energy harvesting is nothing new, with solar power being one of the highest-profile examples. Solar works well for powering parking meters, but if we are going to bring online the packaging and containers that are at the heart of our supply chains—things that are indoors and stacked on top of each other—we need another solution. The technology that gives everyday things like shipping crates both their intelligence and energy- harvesting power are small, inexpensive, stamp-sized computers, printed like stickers and affixed to crates, sweater labels, vials of vaccine, or other objects racing through the global supply chain. These sticker tags, called IoT Pixels, include an ARM processor, Bluetooth radio, sensors, and a security module—basically, a complete system on a chip (SoC). All that’s left is to power this tiny SoC in the most efficient and economical way possible. It turns out, as wireless networks pervade our lives and radio frequency (RF) activity is everywhere, the prospect of recycling that RF activity into energy is the most practical and omni-present solution. There are two primary paths for harvesting RF energy. First, by drawing steady energy from a wireless infrastructure that’s purpose-built to deliver it using radios that cost tens of dollars each. Possible, not practical. Or second, by “scavenging” energy from the radios in the devices that already surround us (phones, Wi-Fi access points, security cameras and smart speakers) and turning their communications transmissions into useable power. It’s this energy scavenging paradigm that finally unlocks the Internet of Trillions and realizes all its benefits. The prospect of harvesting power without additional infrastructure makes an Internet of Trillions self-sustainable. 6G Will Accelerate the Progress To be sure, scavenging RF energy to power an Internet of Everyday Things is by nature unpredictable. But the prospects of self-sustainability (battery-free self-sustainability, no less) are too great to pass up, especially when it comes to supporting a greener planet. Looking ahead, future wireless standards, such as next generation 6G, are likely to include specifications for what the telco industry is calling “Massive IoT” to enable a world of leaner supply chains, traceability, and real-time inventory. Fortunately, solutions exist now. Through an architecture that harvests existing RF energy, reduces power consumption to nanowatts, and communicates as the energy becomes available, engineers have created a platform where everything can be smart. In an Internet of Trillions, self-powered tags mean far greater supply chain efficiency, product safety, and traceability, without requiring expensive infrastructure. Companies around the world are taking advantage today. Download 0.53 Mb. Do'stlaringiz bilan baham: |
