The biggest hurdle in using Wearable Electronic Devices is that they need to be regularly charged. The main problem lies with those devices that are attached to an individual’s body and cannot be conveniently set due to the subpar quality of their batteries. Such as a pacemaker that requires continuous maintenance and replacement of batteries. It would be much better if such devices could be charged in a heartbeat.
Scientists at RMIT University might have been successful at solving this problem. They have created a new piezoelectric material that is 100,000 times thinner than human hair and 800% more efficient than earlier-made piezoelectrics. The material is so successful that it might be able to power pacemakers in the nick of time. This innovation may also lead to a boost in Piezoelectric Materials Market as the essential component used to make these self-powered medical devices is Piezoelectric, in turn increasing the material’s applicability.
Although nano-thin piezoelectric is not exactly a new concept, however, they couldn’t be used before as they were made from toxic materials. The new one is a non-toxic zinc oxide, which is compatible with silicon and can be efficiently utilized in electronics. The new piezoelectric material is printed through liquid zinc oxide. Whenever it is exposed to oxygen, a nano-thin skin is formed, which can be rolled off the surface.
This is a rather intricate process, but scientists still believe that this technology will be profitable. It is because these piezoelectric nano-generators may come to be used in wearable electronics and medical devices, the material can produce electricity when bent leading to peacemakers getting powered through heartbeats or blood pressure itself. For the future, scientists have set their eyes on using this material on ultrasonic devices to be used in defence and infrastructure monitoring. The machines are quite helpful and require low maintenance as their batteries never need to be changed.
There have been several attempts to make implantable medical electronics that could power them. But scientists were adamant about getting the perfect balance between a material's toxicity and its resulting efficiency. Hence, they have finally achieved that through the new nano-generator that is non-toxic and 800% more efficient than other non-toxic piezoelectric materials. Scientists estimated that one 1.1 nano-meter layer of the new material would be able to produce all the energy needed to operate an utterly self-powering nanodevice. Several companies that are involved in the manufacturing of pacemakers and other medical devices can utilize this technology. Besides, it has other uses for it as well, like the material could be used in sensors so that the stresses in buildings could be measured.
