Pragmatic Semiconductor is breaking new ground with Flex-RV, an innovative, flexible, and affordable microprocessor.
Designed on a non-silicon substrate, Flex-RV has embedded machine-learning capabilities and promises to transform industries like wearables, smart labels, and healthcare.
Built on open-source RISC-V architecture and metal-oxide semiconductor technology, Flex-RV is a game-changer for integrating computing power into flexible and disposable devices.
A New Era of Flexibility in Computing
Flex-RV’s unique design allows it to function even when bent or flexed. Traditional processors are made from brittle silicon, limiting their use in flexible electronics.
However, Flex-RV uses Indium Gallium Zinc Oxide (IGZO) Thin-Film Transistors (TFTs), a flexible alternative that reduces the cost of production while offering durability.
These flexible processors allow engineers to create devices that can bend, fold, and be worn comfortably without compromising on performance.
The core of the Flex-RV is a 32-bit processor that is only 17.5 square millimeters in size and packs in around 12,600 logic gates.
Its flexibility doesn’t mean a compromise in functionality; the microprocessor can perform reliably at clock speeds of up to 60 kHz, consuming less than 6 mW of power.
It is so flexible that it can operate even when bent to a radius of 5 millimeters.
Open-Source Design and Affordability
One of the most exciting aspects of the Flex-RV is its use of open-source RISC-V architecture.
This choice eliminates the high licensing fees usually associated with proprietary designs like Intel’s x86, making Flex-RV not only affordable but customizable for specific applications.
The open-source nature of RISC-V gives developers the freedom to tweak the architecture to suit a range of new devices without the financial burden of traditional licensing.
Pragmatic Semiconductor’s Senior Director of Processor Development, Emre Ozer, stated that the company’s goal is to “democratize access to computing.”
Flex-RV’s low-cost, flexible design is aimed at enabling emerging applications that haven’t yet been feasible due to the expense and rigidity of traditional processors.
Industries like healthcare, wearable technology, and consumer goods are expected to benefit significantly, with possibilities ranging from smart bandages to flexible e-labels that track product freshness.
Machine Learning Capabilities on a Flexible Chip
Flex-RV doesn’t just bend to the user’s needs in terms of form—it also offers embedded machine learning capabilities, allowing for smarter, more responsive devices.
This capability could be transformative in sectors like healthcare, where wearable devices could monitor vital signs in real time or predict health issues based on patterns detected through machine learning algorithms.
By integrating computing power and machine learning into flexible, disposable products, Pragmatic is poised to unlock new use cases, from smart packaging to wearable tech that can be seamlessly integrated into everyday life.
Sustainable and Eco-Friendly Innovation
The use of IGZO TFTs in Flex-RV chips also provides environmental benefits. Silicon fabrication processes are notoriously resource-intensive, contributing to significant electronic waste and environmental degradation.
IGZO, on the other hand, offers a more sustainable alternative, with a lower carbon footprint during production.
Moreover, Flex-RV’s flexible nature means it doesn’t require rigid, protective packaging, further cutting down on waste and production costs.
Extensive Testing and Real-World Applications
Pragmatic Semiconductor has rigorously tested Flex-RV to ensure its reliability under various conditions.
It has proven its capability to operate effectively even when bent, opening up exciting possibilities for its application in wearable technology, medical devices, and smart consumer products.
For example, healthcare providers could use disposable smart patches that monitor a patient’s vitals or provide real-time feedback on rehabilitation exercises.
The chip’s low power consumption also makes it ideal for applications requiring long battery life or low-cost energy solutions, such as in smart packaging or environmental monitoring devices.
The Future of Flexible Technology
With Flex-RV, Pragmatic Semiconductor has opened a door to a new era of flexible, affordable computing.
By reducing the cost of microprocessor production and making technology more accessible, Flex-RV has the potential to change how industries approach design and functionality in wearable and disposable products.
As industries adopt this new technology, we may soon see flexible, computing-embedded products in everyday use, from smart labels that monitor food freshness to health-monitoring wearables that blend seamlessly into daily life.
