Selective Inductive Powering in Hardware-Based Paper Computing

We present a method of selective wireless power transferring for paper computing. The novelty of this method lies in the power transmitter can be controlled to selectively activate different receivers in the context of wireless power transferring with multiple receivers. This was achieved by changing the output frequency of the power transmitter and the impedance of the receivers. With this method, users could easily design new types of paper-computing system without worrying about the arrangement of the massive wire connection to power supply. This technology combining with paper computing can become a physical rendering system using paper-crafts, such as paper folding and cutting.
