壓力感應紙 Pressure Sensitive Paper

collective swatch by 陳翊羽 Yiyu Chen & 施惟捷 Wei-Chieh Shih

敘述 Description

此樣片最初是施惟捷的想法，即在紙漿中混合活性炭粉，以製造半導體材料。造紙是HFF的實體工作坊課程之一，楊偉林老師在課程中分享了手工紙的製作經驗。用紙漿混合活性碳的實驗成果在功能方面是有效的，但是成品紙樣很容易沾染，混和活性碳粉也會降低手工紙的結構堅牢度。因此施惟捷決定採用我製作熱變色紙的實驗結構。我用不同的配方製作了幾張樣片，最後採用6層結構和2根不銹鋼紗線作為感應信號線。
樣片的主要概念是使用天然纖維和傳統抄紙技術製作壓力感應介面。與工業用紙相比，構樹纖維手工紙具有相對較鬆的結構，在保持其粘合能力的同時也能在數層之間維持較大空間，且總體上仍具有柔韌性。若將樣片連接到電表，並在兩根不銹鋼絲之間施壓，我們可以觀察到受壓的活性炭導電性變化產生的電阻變化。類似的結構可用作按鈕開關或壓力感應板。
利用傳統工藝技術製造電子元件的實驗能開啟重新定義工藝邊界的討論，或提供新的可能性。在社會和生活方式很大程度的變化中，傳統工藝仍能啟發靈感，也能被啟發。

This swatch is originally Shih Wei Chieh’s idea of mixing active charcoal powder in paper pulp, in order to make semi-conductive material. Paper making is one of HFF workshops; the lecture during physical residency was Yang Wei-Lin, who shared her experience of hand sheet paper making. The experiment with paper pulp was effective on functional aspect, but the outcome was highly staining and charcoal powder could reduce the firmness of this hand-made paper. Therefore Shih decided to adapt the construction of my experiment with Thermochromic paper. I made several tryouts with different formula, and finally settled with a 6 layered construction and 2 pieces of stainless steel yarn as sensing wire.
The idea is make a pressure sensitive interface with natural fiber and traditional crafting technique. Hand-made paper with paper mulberry fiber has a relatively loose structure compare to industrial paper sheet; while remain its bonding ability, hand-made paper maintain a larger space between its multiple layers and in general still being flexible. When we link this swatch to an electric meter and press across the space between those two piece of stainless yarns, we could observe the resistance change resulting from compressed active charcoal power. Similar construction could be used as push button switch or pressure sensing board.
In my opinion, the experiments of making electronic element with traditional crafting technique open up the possibility and discussion of how we could redefine the boundary of traditional craft. While the society and lifestyle is intensely changing, traditional craft technique could still inspire and being inspired.
