“…The printed pattern is flexible, and conductivity can be established almost immediately after printing. Since it also has the advantage of low-cost prototyping, many studies have used this technique to fabricate sensors [4,6,9,16,20,33], NFC antennas [22], multilayered circuits [31], and displays [21]. Although Kawahara et al 's method enables users to create a circuit without any post-processing steps such as sintering, the printed circuits are of low durability [20].…”

Due to its natural warmth, wood is frequently used to produce touchable objects such as furniture and signboards. Laser cutting machines are becoming common in personal wood processing to cut and engrave wood. In this paper, we propose a method and workflow for producing various sensors and electrical circuits for interactive devices by partially carbonizing the wood surface with a laser cutting machine. Similar to wiring on a conventional printed circuit board (PCB), the carbonized part functions as a conductive electrical path. A method for creating electronic circuits and sensors made of carbon graphene on botanical materials has been proposed. This technique makes use of a raster-scanning femtosecond (fs) laser, which is less common for personal fabrication than a constant-wave (CW) laser. Moreover, raster-scanning requires a substantial amount of time to create a circuit that is mainly made of conductive lines. This paper extends the method with a defocused vector-scanning CW laser beam and reduces the time and cost required for fabrication. The proposed method uses an affordable CW laser cutter to fabricate an electrical circuit, including touch sensors, damage sensors, and load sensors on wood boards. The circuit can be easily connected to traditional PCBs and electric parts such as one-board microcomputers using metal screws and nails typically used in DIY woodworking. We develop ease of use software design tool that supports the creation and fabrication of carbon paths. In addition, we report on a series of investigations, including optimizing wood materials and laser parameters to establish design guidelines.

“…Researchers have used these methods to fabricate a wide variety of interactive elements such as touch sensors [8,13,24], bend sensors [25], pressure sensors [4], NFC antennas [18], multilayered circuits [22], and active light-emitting displays [17] on a paper substrate. Techniques to integrate these elements with various paper-based structures have also been explored.…”

In this pictorial, we propose an approach to integrate electronics into a paper-woven craft. A paper-woven structure is formed by alternately and orthogonally weaving paper strips. The key idea is to add conductive layers to these strips by printing or transferring conductive materials. Our approach enables us to form the skeleton of an object and its wiring and sensor arrangement simultaneously. We explore the creative space of this approach, i.e., integrating functions such as sensing, display, and sound amplification into objects, for leveraging the paper-woven structure. We also outline the workflow of the approach, introduce a design support tool, and discuss example applications that combine the electronic-enabled functionality and woven structure.
