Battery-less Solutions Flood In, Explores IDTechEx
Complementary to this is a newly-announced implanted defibrillator and heart pacemaker. Researchers at Northwestern and George Washington universities have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it is no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body's biofluids over the course of five to seven weeks, without needing surgical extraction.
The device wirelessly harvests energy from an external, remote antenna using near-field communication protocols — the same technology used in smartphones for electronic payments and in RFID tags. This eliminates the need for bulky batteries and rigid hardware, including wires.
said Northwestern's John A. Rogers , who led the device's development.
Raghu Das CEO of IDTechEx notes that,
Hill Air Force Base in Utah is involved in a demonstration project to use small, very low-wattage sensors by Everactive to monitor the health of steam delivery and mechanical systems, electric motors, pumps, fans, and other rotating devices. These always-on wireless sensors deliver continuous cloud-based analytics at a scale not possible with battery-powered devices.
Everactive targets high-volume industrial assets that are currently unmonitored or under-monitored precisely because they exist in such a high volume. Indeed, they point out that most plants are unwilling to place battery-powered sensors on thousands of motors, pumps, compressors, or steam traps; the logistical cost of adding thousands of items to a maintenance list is not only prohibitive but also defeats the cost-saving purpose of those very sensors.
The new investors joined existing investors including New Enterprise Associates, which counts former General Electric CEO Jeff Immelt as a Venture Partner and key advisor to its portfolio of industrial companies.
Wireless tire pressure monitoring systems are progressing by use of surface acoustic waves, electromagnetic H fields, and other means. Nuclear Diamond Battery (NDB) has created a microchip with a radioactive heart that claims to last 28,000 years without ever needing a charge. i4 Product Design now has a feasibility study, funded by a grant from Scottish Enterprise, to explore how energy harvesting can power electronics and the Internet of Things.
Android now has documentation on how it handles products that have no internal batteries. 6G Communications that is expected in 2030 will revolve around devices with the lowest power so energy harvesting suffices and even devices without power, the device being driven by the 6G signal beam rather like battery-less RFID by backscatter. Call it Wireless Information and Energy Technology (WIET) and learn the full detail of this specific in IDTechEx report, "6G Communications Market, Devices, Materials 2021-2041".
