Wireless charging is important for IoT



From ordinary suburban homes to product assembly lines, "smart" technology seems to be reinforcing every corner of our lives. However, while IoT technology seems to be everywhere, continuing to power these devices remains a challenge, and if this problem is not resolved, many exciting potential IoT applications may not eventually become viable.

More than 30.7 billion IoT devices will be brought to the market by 2020, almost double the 15.4 billion IoT devices recorded in 2015, and by 2025 it is estimated to reach 75.4 billion. If you still use current alkaline batteries and wired chargers to power all of these technology products, you obviously do not work. Then, the most inevitable and most effective solution is to wirelessly charge IoT devices for wireless communications. The question is, when will this long-range wireless charging solution emerge? The answer may not be that far ...

Dialog is working closely with its partner Energous to bring the DA4100 RF transmit IC to the mass market this year. The DA4100 is a complete system-on-chip for a highly integrated, smaller, cost-effective WattUp® wireless power launch system. This solution can be key to unlocking the full potential of IoT as it can sustain devices of any type from a few millimeters to a few meters by delivering enough power wirelessly.

Future home should not be characterized by cables

For example, at home, the number of devices that currently require batteries or cables may exceed three digits. This includes sensors that support security systems, or security alerts for fire or carbon monoxide monitoring - these technologies save lives and ensure safety only with uninterrupted power on. If consumers double the number of IoT devices used in the home environment over the next five years, they must find ways to keep the power strip plugged into every wall outlet.

This becomes a crucial factor when it comes to the economics of home ownership, as more and more Americans are now renting houses instead of buying a home, which limits their right to modernize their homes . So, if anyone wants to load IoT thermostats and doorbells into their homes to reduce power costs and increase security, wireless charging allows them to adopt the latest technology without being limited to cabling limit.

Industry 4.0 can not be achieved without wireless power management

In the industrial arena, the impact can be even greater, as the entire plant may be down if any of the sensors in the work flow goes down. The current average cost of industrial sensors is about $ 50, but the wiring costs for their continued power supply could exceed $ 1,000. These cable-powered sensors usually have no backup power. Although the sensors themselves can be defined as wireless solutions using Bluetooth low energy technology to communicate with each other, they still have to rely on potentially failing cables to stay running.

In this case, the wireless power will help to truly get a hold on Industry 4.0 and help businesses reduce the cost of their power management infrastructure. Wireless Charging Redundant solutions can be deployed to place multiple wireless power transmitters within the receive range of each sensor, ensuring that if one transmitter fails, the other transmitter can act as a backup.

Wireless charging is bound to have the same universal WiFi, security and range. Energous, which has received regulatory approvals in the United States to deploy proximity wireless charging technology (Near Field Technology), has benefited IoT devices such as wearable devices and earbuds. There is currently ongoing regulatory approval of midfield technology that extends the distance between transmitters and IoT receivers to a few feet, enabling more and more IoT applications to benefit from long-range wireless charging. In the end, we'll see the emergence of wireless charging in the entire room that supports long-distance charging up to 5 meters (far field). We are working hard to continuously improve the level of wireless charging capabilities through our partnership with Energous.
