➀ A non-silicon flexible and programmable chip has been developed by scientists. It features a low-power 32-bit microprocessor that can operate when bent and run machine learning workloads. The open-source RISC-V architecture of the chip suggests it could cost less than a dollar, making it suitable for wearable medical electronics, smart packaging labels, and other inexpensive items. ➁ The chip, named Flex-RV, is a 32-bit microprocessor based on indium gallium zinc oxide (IGZO) and is designed to be much cheaper than silicon processors. ➂ RISC-V, introduced in 2010, aims to create smaller, lower-power, and more powerful processors by simplifying the core instruction set they can execute. It is free and open-source, allowing chip designers to avoid expensive licensing fees associated with proprietary architectures like x86 and ARM.
