    Miniature processor chips are present in almost every electronic device these days, from the simplest to the most sophisticated, such as smartphones and computers, and even the idea of life seems impossible without them. Arm, whose processing achievement can be seen on all mobile devices from mobile phones and tablets to countless wearable devices, is set to take the microchip experience one step further to realize the idea of the Internet of Everything. Arm recently published an article in the scientific journal Nature announcing the construction of an integrated chip on a plastic substrate called PlasticARM.

    The flexible PlasticARM chip introduced in this scientific paper is not limited to details and theoretical topics, and Arm is an example of it in the real world. Also available for presentation; Although not the first flexible model of its kind, the PlasticARM is practically the most sophisticated, with a 32-bit Cortex-M0 processor (the simplest and cheapest processing core in the Arm Cortex-M family), 456-byte RAM, and We consume 128 bytes of RAM. The suite houses more than 18,000 logic gates, which the company says are at least 12 times larger than previous plastic-based chips. The number of components in this chip reaches 56,340, which is also unrivaled in this field compared to its counterparts.

    This chip, which was made in collaboration with a well-known manufacturer of flexible electronics called PragmatIC, is still operating in It does not have the level of silicon-based designs and, for example, is still only able to run test programs that have already been physically embedded in it during production. This, of course, is the first step, and Arm researchers have announced work on future versions with the possibility of installing new code.

    Metal-oxide thin-film transistors, which rely on this technology and unlike processors based on brittle silicon internal components, will be able to print on flexible and curved surfaces without any problems. This allows different processors to be easily printed on materials such as plastic and even paper. In this article, Arm researchers discuss the application of PlasticARM technology to place microchips in a variety of conditions that by today's standards still seem impossible and costly. Examples are chips that can be printed on the bottle to detect spoilage of the contents of the bottle and replace the expiration date. This kind of use, according to Arm, creates a new kind of "Internet of Everything" idea that will be embedded in more than a trillion different objects in the next decade. Plastic-based chips, of course, still have some downsides, and at least in the short term, they will not be able to bypass silicon processors in normal use; Among these negatives should be noted their low efficiency in terms of energy consumption, density and performance. For example, PlasticARM, discussed in this article, consumes 21 mW of energy, but 99% of this energy is practically 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 PlasticARM has an area of 59.2 square millimeters, which (according to AnandTech) is nearly 1,500 times larger than the Cortex-M0-like silicon processor! Such microchips, of course, do not require much speed and energy efficiency, as James Myers, one of Arm's research engineers, told New Scientist: "This [chip] will not be fast, it will not be energy efficient. "It did, but I want to put it on a lettuce to track its durability. That's the idea [of this chip]."
