Interesting. Supposedly will cost less than $1 USD to manufacture thus 32 bit processor
Bendable non-silicon RISC-V microprocessor - NatureFlex-RV, a 32-bit microprocessor based on an open RISC-V instruction set fabricated with indium gallium zinc oxide thin-film transistors on a flexible polyimide substrate, enables an ultralow-cost bendable and flexibleĀ microprocessor.
