Selective inductive powering system for paper computing

Abstract

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-craft, such as paper folding and cutting. In this paper we describe the implementation of our method, the advantages and limitations, the applications and the future directions.

FluxPaper

“…Saul et al describe several types of paper designs for actuation and interactive systems by instructing with LED lights for folding [7], and with the SMA to actuate the paper [12,18,19,21,28]. Though ideas of using SMA tend to use wired designs for the paper, Koizumi et al [12] consider a wireless method for moving the paper with SMA heating by laser irradiation.…”

“…Though ideas of using SMA tend to use wired designs for the paper, Koizumi et al [12] consider a wireless method for moving the paper with SMA heating by laser irradiation. In addition, there is the idea of using power transmission via electromagnetic induction on the paper material [28,29]. Paper material research by Figueiredo et al [3] changes the shape of paper by heat caused by electricity and makes it possible to build an executable robot structure.…”

Move-it sticky notes providing active physical feedback through motion

“…However, while the combination of a common paperclip with SMA is relatively simple from a design perspective, the technology comes with limitations like heating problems, speed limitations due to dependency on environmental parameters (e.g., temperature), and need of wiring to provide power supply for actuation [15,21]. Potential solutions addressing these issues will be investigated in our future work include the use of Peltier elements for controlling SMA temperature, selective inductive powering to reduce external wiring [26], and exploration of ferromagnetic SMA that changes shape in response to magnetic fields.…”

AutoGami

“…We developed our toolkit based on the technology of selective inductive power transmission [29]. Compared with the movable craft toolkits we described previously, ours doesn't require users to consider the design of the circuit and wire connection.…”

“…AutoGami's software interface allows users to plan a variety of paper craft movements: its use of selective inductive power transmission [29] allows users to control aspects of movement such as duration, amplitude, and sequence without concerning themselves with technical implementation. Compared with previous work on automated paper craft (Table 1 and Table 2), AutoGami provides additional controllability and customizability.…”
