Small, flexible and twistable micro or nanoelectronics have great potential to change the medical history.
Continuous and long term monitoring of tissues and organs could further aids the prolongevity of patients and build a better database on medical history of specific individual for ease of diagnosis and therapy.
Researchers at the National Institute of Standards and Technology (NIST) has overcame a major hurdle on this front and has achieve breakthrough in computer memory by creating a flexible novel memory unit could handle quite a bit of squeezing.
According to authority source, it is inexpensive and could be easily manufactured.
â€œWe have fabricated a lightweight memory device,â€ says Nadine Gergel-Hackett, one of the researchers on the project, â€œthat uses transparencies seen in overhead projectors as the material for its flexible sheet.â€
Current silicon and circuit-board technology requires memory’s components to be flat and rigid. But flexible components would open up a whole new class of possibilities. For instance, they could be used to create small medical sensors to monitor heart rate or blood sugar, and considering the less energy consumption takes to run this flexible device, it could even further aid to creation of flexibly adaptive and eco-friendly pc or laptop in the long run.
Gergel-Hackett and her colleagues took polymer sheets and deposited a thin film of titanium oxide on their surfaces. To deposit the titanium oxide, they used a sol gel process that consists of spinning the material in liquid form and letting it set, similar to how gelatin is made.
They added electrical contacts and created a flexible memory switch that operates on less than 10 volts.
The device is said could maintain its memory when power is lost and can function even after being flexed more than 4,000 times… WOW!
The flexible memristor is still in the prototype stage and faces some challenges before it can be ready to market.
But still, reliability and consistency issues between the different devices made are still exists, says Gergel-Hackett.
But due to ease of its fabrication process, she hopes some day it can be as easy to print a flexible memory component as it is to print a slide on a transparency.
