This National Science Foundation (NSF) Computer and Information Science and Engineering (CISE) Federal Grant Program (CFDA 47.070) award to Carnegie Mellon University in the amount of $203,855 supports the development of new technology to bridge the gap between paper objects and computer systems. The project aims to create interactive paper devices that can transmit data without requiring batteries or other on-board electronics, using techniques like backscatter radio to reflect or absorb radio waves sent from an external device. The goal is to combine the advantages of paper-based interfaces with the functionality of connected digital systems, enabling everyday paper objects like calendars and grocery lists to take advantage of computer integration. Key focus areas include developing low-cost antenna designs and paper-based mechanisms to alter the antenna characteristics through physical manipulation. This 3-year project, starting October 1, 2024, will advance the state of battery-free, ultra-low-cost interactive devices on paper substrates.
