Introducing PlasticARM, Arm plastic microchip – processing from lettuce leaves to milk bottles! Small and miniature processing chips these days are almost All electronic devices from the simplest to the most complex, such as smartphones and computers, are present, and even imagining life without them seems impossible. The Arm company, whose processing achievements can be seen in all mobile devices from mobile phones and tablets to countless wearable devices, is going to take the experience of small microchips one step further in order to realize the idea of ​​the internet of everything. Arm company has recently published an article with /a> in the scientific journal Nature announced the construction of an integrated chip on a plastic substrate called PlasticARM.

PlasticARM flexible chip introduced in this scientific article is not only limited to details and theoretical issues, and Arm is an example It is also available in the real world to present; Despite the fact that PlasticARM is not considered the first flexible example of this type, it is practically the most complex one, and its structure includes a 32-bit Cortex-M0 processor (the simplest and cheapest processing core in the Cortex-M family of Arm company), 456-byte RAM memory and We use 128 bytes of RAM. This set includes more than 18,000 logic gates, which, according to the manufacturer, is at least 12 times more than previous plastic-based chips. The number of components present in this chip reaches 56,340, which is unrivaled in this field as well. It does not have the level of silicon-based designs and, for example, is still only able to run test programs that are already physically embedded in it during production. Of course, this is the first way and Arm researchers have announced the work on future versions with the possibility of installing new codes.

What plays a fundamental role in the appeal of PlasticARM and other similar chips in this category naturally Their application is in flexible components and specifically in this case in metal-oxide TFTs (metal-oxide thin-film transistors), which rely on this technology and unlike processors based on fragile silicon internal components, it is possible to print on flexible surfaces without causing problems. And they will have the bender. Thus, it is possible to easily print different processors on materials such as plastic and even paper.

In this article, Arm researchers talk about the use of PlasticARM technology to place microchips in various conditions that are still impossible and costly by today’s standards. For example, we can refer to the chips that, by printing on the bottle of milk, will be able to detect the spoilage of the contents of the bottle and replace the use-by date. This type of user, called Arm, creates a new kind of “Internet of everything” idea, which will be embedded in more than a trillion different objects in the next decade.

Plastic-based chips, of course, still have certain negative points and at least in the short term, they will not be able to replace silicon processors in normal use; Among these negative things, we should mention their low efficiency in terms of energy consumption, density and performance. For example, the PlasticARM discussed in this article consumes 21 milliwatts of energy, but 99% of this energy is actually wasted and only 1% of it is used for computing. The next point is their size and density, which again PlasticARM can be considered as an interesting example; The area of ​​PlasticARM is declared equal to 59.2 mm square which (according to AnandTech) is nearly 1,500 times larger than the equivalent silicon Cortex-M0 processor! Such microchips, of course, do not need much speed and optimal energy consumption, as far as James Myers, one of Arm’s research engineers in this field, in
