Description

Sensors and Sensing Devices

本發明，關於感測器及感測裝置。The present invention relates to sensors and sensing devices.

作為檢測水分的水分感測器，提案有利用水分接觸一對電極之際所產生的電動勢者。例如，在文獻1(日本特開2015-229003號公報)，記載有感電模組，其具備在具有接收排泄物之吸收體的穿著物品。該感電模組，具有以離子化傾向不同的材料所構成的一對電極，前述一對電極之中的至少一方，是具有骨格部及設在該骨格部之間的空隙部的骨格構造。而且，前述一對電極與排泄至前述吸收體的尿接觸，藉此產生電動勢。但是，文獻1所記載的感電模組中，作為電極，是使用碳印刷薄片或鋁薄片等之薄片構件。因此，在薄片構件較厚的情況，會欠缺可撓性，在薄片構件較薄的情況，有欠缺耐久性的問題。於是，要求著可撓性及耐久性優異的感測器。且，若可將該感測器作為織物等之絲線來織入的話，可容易且省空間地安裝在穿著物品等。 As a moisture sensor for detecting moisture, there has been proposed one that utilizes an electromotive force generated when moisture contacts a pair of electrodes. For example, Document 1 (Japanese Patent Laid-Open No. 2015-229003 ) describes an electroconductive module provided with a wearing article having an absorber that receives excrement. The electroconductive module includes a pair of electrodes made of materials with different ionization tendencies, and at least one of the pair of electrodes has a skeleton structure having a skeleton portion and a void portion provided between the skeleton portions. And the said pair of electrodes generate|occur|produces the electromotive force by contacting the urine excreted to the said absorber. However, in the electroconductive module described in Document 1, a sheet member such as a carbon-printed sheet or an aluminum sheet is used as the electrode. Therefore, when the sheet member is thick, flexibility is lacking, and when the sheet member is thin, there is a problem that durability is lacking. Therefore, a sensor excellent in flexibility and durability is required. Furthermore, if the sensor can be woven as a thread of a fabric or the like, it can be easily and space-savingly attached to a wearing article or the like.

[第一實施形態] 以下，針對本發明舉出實施形態為例，基於圖式來說明。本發明並不限定於實施形態的內容。又，在圖式中，有為了容易說明而擴大或縮小來圖示的部分。 (感測器) 本實施形態的感測器100，如圖1及圖2所示般，具備第一配線11、第二配線12、非導電性線狀體21。第一配線11及第二配線12，各自含有導電性線狀體。非導電性線狀體21的根數為六根。六根非導電性線狀體21與第一配線11及第二配線12，是被纏繞而成為撚絲。第一配線11與第二配線12，成為沒有互相接觸。而且，在第一配線11及第二配線12之間，有物質接觸的情況時，可藉由感測器100來感測該物質。作為可感測的物質，只要是可供電氣流動之流動體的話，並未特別限定。具體來說，可舉出液體、及凝膠狀的流動體等。更具體來說，可舉出水、尿、及血液等。作為特佳的物質，可舉出含有水分的物質。而且，感測器100，是水分感測器為佳。 (配線) 本實施形態的感測器100，只要具備兩個以上的配線即可，至少具備第一配線11及第二配線12即可。例如，除了第一配線11及第二配線12以外，還具備其他配線(未圖示)亦可。第一配線11及第二配線12，各自含有導電性線狀體。第一配線11及第二配線12，含有複數根導電性線狀體亦可。且，第一配線11及第二配線12，含有導電性線狀體以外的其他連接材料(銲錫、及導電性塗料等)或連接構件(連接器等)亦可。 (導電性線狀體) 第一配線11及第二配線12所使用的導電性線狀體，只要具有導電性的話，並無特別限制，但可舉出含有金屬導線的線狀體、及含有導電性絲的線狀體等。導電性線狀體，是含有金屬導線及導電性絲的線狀體(將金屬導線與導電性絲予以扭成的線狀體等)亦可。又，在本說明書中，線狀體，是指線狀的構件。線狀體的長度，例如1cm以上。線狀體的形態並未特別限定，是一根線狀的構件亦可，是由複數根線狀的構件所成的集合體亦可。線狀體的剖面形狀，可因應線狀體的形態而成為各種形狀。含有金屬導線的線狀體、及含有導電性絲的線狀體，皆具有較高的電氣傳導性，故適用於導電性線狀體的話，容易降低第一配線11及第二配線12的電阻。作為金屬導線，可舉出含有以下素材的導線：銅、鋁、鎢、鐵、鉬、鎳、鈦、銀、及金等之金屬，或是含有兩種以上金屬的合金(不銹鋼、碳鋼等之鋼鐵、黃銅、磷青銅、鋯銅合金、鈹銅合金、鐵鎳合金、鎳鉻合金、鎳鈦合金、鐵鉻鋁合金、赫史特合金和錸鎢合金等)。且，金屬導線，是被錫、鋅、銀、鎳、鉻、鎳鉻合金、及銲錫等鍍敷者亦可，被後述之碳材料或聚合物覆蓋表面者亦可。作為金屬導線，亦可舉出被碳材料覆蓋的金屬導線。金屬導線，被碳材料覆蓋的話，能抑制金屬腐蝕。作為覆蓋金屬導線的碳材料，可舉出：無定形碳(碳黑、活性碳、硬碳、軟碳、介孔碳、及碳纖維等)、石墨、富勒烯、石墨烯、及奈米碳管等。作為含有導電性絲的線狀體，是由一根導電性絲所成的線狀體亦可，將複數根導電性絲予以扭成的線狀體亦可。且，是將導電性絲與絕緣性絲予以扭成者亦可。含有導電性絲的線狀體，與含有金屬導線的線狀體相較之下，柔軟性較高，有著難以發生斷線的優點。作為導電性絲，可舉出：含有導電性纖維(金屬纖維、碳纖維、及離子導電性聚合物纖維等)的絲、含有導電性微粒子(奈米碳粒子等)的絲、在表面鍍敷或蒸鍍有金屬(銅、銀、及鎳等)的絲、及浸泡過金屬氧化物的絲等。作為含有導電性絲的線狀體，特別是，作為奈米碳粒子，較佳可舉出：含有奈米碳管的絲(奈米碳管絲)的線狀體(以下亦稱為「奈米碳管線狀體」)。奈米碳管線狀體，例如，從奈米碳管叢(使奈米碳管對於基板於垂直方向配向地在基板上複數成長而成的成長體，亦有稱為「陣列」的情況)的端部，將奈米碳管拉成薄片狀，將拉出的奈米碳管薄片集束之後，纏繞奈米碳管束而得到。這種製造方法中，在纏繞之際沒有施加扭力的情況，得到絲帶狀的奈米碳管線狀體，在有施加扭力的情況，得到絲狀的線狀體。絲帶狀的奈米碳管線狀體，是不具有複數個奈米碳管之集合被扭繞的構造的線狀體。此外，從奈米碳管的分散液，亦可藉由紡絲等來得到奈米碳管線狀體。紡絲所致之奈米碳管線狀體的製造，例如，可藉由美國公開公報US2013/0251619(日本國特開2011-253140號公報)所揭示的方法來進行。就能夠得到奈米碳管線狀體之直徑之均勻度的觀點來看，使用絲狀的奈米碳管線狀體為佳，就能夠得到純度較高之奈米碳管線狀體的觀點來看，藉由纏繞奈米碳管薄片來得到絲狀的奈米碳管線狀體為佳。奈米碳管線狀體，是兩根以上的奈米碳管線狀體彼此纏繞而成的線狀體。奈米碳管線狀體，是含有奈米碳管、金屬、導電性高分子、或石墨烯等之奈米碳管以外之導電性材料的線狀體(以下亦稱為「複合線狀體」)亦可。複合線狀體，容易一邊維持奈米碳管線狀體的上述特徵，一邊提升線狀體的導電性。作為複合線狀體，例如，以含有奈米碳管與金屬的線狀體為例的話，可舉出：(1)從奈米碳管叢的端部將奈米碳管拉成薄片狀，將拉出的奈米碳管薄片集束之後，纏繞奈米碳管之束來得到奈米碳管線狀體，在這過程中，在奈米碳管叢、薄片或束、或纏繞而成的線狀體的表面，藉由蒸鍍、離子鍍、濺射、噴塗、或濕式鍍敷來載持金屬單體或金屬合金而成的複合線狀體；(2)使奈米碳管之束與金屬單體的線狀體或是金屬合金的線狀體或複合線狀體纏繞而成的複合線狀體；(3)使奈米碳管線狀體或複合線狀體與金屬單體的線狀體或是金屬合金的線狀體或複合線狀體纏繞而成的複合線狀體等。又，(2)的複合線狀體中，在纏繞奈米碳管之束之際，與(1)的複合線狀體同樣地對奈米碳管載持金屬亦可。且，(3)的複合線狀體，是由兩根線狀體編成之情況的複合線狀體，但只要包含有至少一根金屬單體的線狀體或是金屬合金的線狀體或複合線狀體的話，合編奈米碳管線狀體或金屬單體的線狀體或是金屬合金的線狀體或是複合線狀體之三根以上亦可。作為複合線狀體的金屬，例如，可舉出金屬單體(金、銀、銅、鐵、鋁、鎳、鉻、錫、及鋅等)、以及含有該等金屬單體之至少一種的合金(銅-鎳-磷合金、及銅-鐵-磷-鋅合金等)。該等在導電性線狀體之中，以含有奈米碳管絲的導電性線狀體(特別是，僅含有奈米碳管絲的導電性線狀體，或是含有奈米碳管絲與非金屬系導電性材料的導電性線狀體)為佳。例如，在表面鍍敷或蒸鍍金屬(銅、銀、及鎳等)而成的絲、浸泡過金屬氧化物的絲，若反覆伸縮的話金屬或金屬氧化物容易裂開，耐久性較低。在此點，奈米碳管線狀體，對撓曲的耐性較強，即使反覆伸縮，電阻值也難以變化。且，奈米碳管線狀體，有著耐蝕性亦高的優點。在此，導電性線狀體的線電阻(電阻率)是5.0×10 ^-3Ω/cm以上1.0×10 ³Ω/cm以下為佳，1.0×10 ^-2Ω/cm以上5.0×10 ²Ω/cm以下較佳。若為使用導電性高之金屬的導電性線狀體的話，導電性線狀體的線電阻可為前述下限以上。另一方面，只要導電性線狀體的線電阻在前述上限以下的話，即使是配線的路徑變長的情況亦可將電阻抑制成較低，可抑制配線本身成為電阻體而對計測器造成負載的問題。導電性線狀體之線電阻的測量，是如下述。首先，在導電性線狀體的兩端塗布銀膏，測量銀膏之間之部分的電阻，求出導電性線狀體的電阻值(單位：Ω)。然後，將所得到的電阻值除以銀膏間的距離(cm)，算出導電性線狀體的線電阻。導電性線狀體之剖面的形狀，並未特別限定，可為多角形狀、扁平形狀、橢圓形狀、圓形狀等，但就容易與非導電性線狀體21纏繞等的觀點來看，以橢圓形狀、圓形狀為佳。導電性線狀體之剖面為圓形狀的情況時，導電性線狀體的直徑D(參照圖2)，是2μm以上1000μm以下為佳，2μm以上500μm以下較佳。且，就可撓性及耐久性的觀點來看，導電性線狀體的直徑D，是5μm以上300μm以下較佳，10μm以上100μm以下更佳。導電性線狀體之剖面為橢圓形狀的情況時，長徑是在與上述直徑D相同的範圍為佳。且，導電性線狀體之剖面為多角形狀的情況時，多角形之外接圓的直徑是在與上述直徑D相同的範圍為佳。導電性線狀體的直徑D，是使用數位顯微鏡，觀察導電性線狀體的剖面，測量導電性線狀體的直徑，取出其平均值。 (非導電性線狀體) 非導電性線狀體21，只要是不具有導電性的線狀體的話，並無特別限制，但可舉出天然纖維、合成纖維、及半合成纖維等。作為天然纖維，可舉出綿、麻、絲綢、羊毛、及羊絨等。作為合成纖維，可舉出聚酯纖維、尼龍、及丙烯酸纖維等。作為半合成纖維，可舉出人造絲、莫代爾、天絲、銅氨纖維、醋酸鹽纖維、二醋酸鹽纖維和三醋酸鹽纖維等。如本實施形態般，配線根數為兩根的情況，只要非導電性線狀體21的根數為六根以上的話，可成為第一配線11與第二配線12不互相接觸的撚絲。配線根數為兩根的情況，非導電性線狀體21的根數以六根以上為佳，10根以上較佳，14根以上特佳。且，就使感測器100更為精密的觀點來看，非導電性線狀體21的根數為30根以下為佳。就同樣的觀點來看，非導電性線狀體21的根數，是配線之根數的3倍以上為佳，配線之根數的5倍以上較佳，配線之根數的8倍以上特佳。非導電性線狀體21之剖面的形狀，並未特別限定，可為多角形狀、扁平形狀、橢圓形狀、圓形狀等，但就容易與導電性線狀體纏繞等的觀點來看，以橢圓形狀、圓形狀為佳。非導電性線狀體21之剖面為圓形狀的情況時，非導電性線狀體21的直徑，是2μm以上1000μm以下為佳，2μm以上500μm以下較佳。且，就容易與導電性線狀體纏繞等的觀點來看，非導電性線狀體21的直徑，是5μm以上300μm以下較佳，10μm以上100μm以下更佳。非導電性線狀體21之剖面為橢圓形狀的情況時，長徑是在與圓形狀之情況之非導電性線狀體21的直徑相同的範圍為佳。且，非導電性線狀體21之剖面為多角形狀的情況時，多角形之外接圓的直徑是在與圓形狀之情況之非導電性線狀體21的直徑相同的範圍為佳。且，就容易與導電性線狀體纏繞或性能展現性的觀點來看，非導電性線狀體21對第一配線11及第二配線12(導電性線狀體)的直徑比(非導電性線狀體/導電性線狀體)，以1/5以上5以下為佳，1/3以上3以下較佳，1/2以上2以下更佳，1以上3/2以下特佳。非導電性線狀體21的直徑，是使用數位顯微鏡，觀察非導電性線狀體21的剖面，測量非導電性線狀體21的直徑，取出其平均值。 (感測裝置) 接著，針對本實施形態的感測裝置來說明。本實施形態的感測裝置，如圖3所示般，具備：感測器100、感測配線間之電位差的感測模組4、以及傳輸無線訊號的無線傳輸模組5。且，感測器100，接觸於被裝體3。被裝體3，是安裝感測器100的對象，並未特別限定。被裝體3，亦可為能變形者，亦可為有凹部、凸部或曲面者。本實施形態的感測器100為絲狀，可撓性及耐久性優異，故亦適合用在這種被裝體3。且，被裝體3，亦可為紡織物、及編織物等。本實施形態的感測器100為絲狀，故可對於被裝體3紡織或編織感測器100。感測模組4，具備第一電極41與第二電極42。第一電極41，電性連接於第一配線11，第二電極42，電性連接於第二配線12。而且，對第一電極41及第二電極42，藉由電池(未圖示)施加電壓的情況，當物質接觸到被裝體3之第一配線11及第二配線12之間的情況時，電壓會變化，故可藉由感測器100感測到該物質。無線傳輸模組5，在藉由感測模組4感測到物質的接觸時，朝向圖4所示的無線中繼局6傳輸無線訊號。無線中繼局6，接收到從無線傳輸模組5傳輸的無線訊號，對於感測伺服器7傳輸表示無線訊號已被傳輸之事的訊號。感測感測器7，接收到來自無線中繼局6的訊號時，基於該訊號，感測到物質接觸到感測器100之事，因應必要來記錄在資訊處理終端(未圖示)。本實施形態的感測裝置中，配線之中的一個(第一配線11)與另一個(第二配線12)(以下亦將該等配線彼此稱為「相鄰的配線」)，各自的材質不同，該等之材質的離子化傾向不同為佳。若為這種構造的話，即使是沒有電池的情況，只要物質接觸到第一配線11及第二配線12之間的話，就會發生電動勢，故可藉由感測器100來感測到該物質。第一配線11及第二配線12之表面的材質，例如為：鋁(-1.676V)、鈦(-1.63V)、鋅(-0.7626V)、鉻(-0.74V)、鐵 (-0.44V)、鎳(-0.257V)、錫(-0.1375V)、銅(0.340V)、銀(0.7991V)、金(1.52V)、及碳等。又，上述括弧內的數值，是離子化傾向的數值。且，在本說明書，關於碳，是取代當成氫的離子化傾向之數值亦即0V。相鄰之配線表面的材質間的離子化傾向之差，就電動勢的觀點來看，以0.5V以上為佳，0.8V以上較佳，1.1V以上更佳。做為相鄰之配線表面的材質較佳的組合，可舉出：鋁與碳的組合、鋁與銅的組合、鈦與碳的組合、鈦與銅的組合、鋅與碳的組合、鋅與銅的組合、鋅與銀的組合、及鋅與金的組合等。 (第一實施形態的作用效果) 根據本實施形態，可發揮如下的作用效果。 (1)本實施形態中，第一配線11及第二配線12含有導電性線狀體，故可提供絲狀且可撓性及耐久性優異的感測器100。 (2)第一配線11與第二配線12被纏繞成絲狀，故該等之間隔非常窄。因此，即使是較少量的物質亦可感測，感測性能較高。 (3)導電性線狀體，是直徑D為2μm以上1000μm以下的線狀體，故與金屬箔等相較之下，耐撓曲性較高。因此，導電性線狀體，可容易撓曲，且耐久性亦高，故可提供可撓性及耐久性優異的感測器100。且，與金屬箔等相較之下難以成為凸部，且接觸面積亦較少。因此，例如，在被裝體3為衣類等接觸於肌膚者時，與金屬箔等相較之下，在肌膚觸感良好這點較佳。 (4)相鄰之配線亦即第一電極41及第二電極42的材質不同，該等之材質的離子化傾向不同。因此，即使是沒有電池的情況，只要物質接觸到第一配線11及第二配線12之間，就會發生電動勢，故可藉由感測器100來感測到該物質。 [第二實施形態] 接著，基於圖式來說明本發明的第二實施形態。本實施形態的感測器100A，如圖5所示般，將第一配線11、第二配線12、六根非導電性線狀體21，予以編織成細繩。在本實施形態，除了使第一配線11、第二配線12、六根非導電性線狀體21成為細繩以外，是與第一實施形態相同的構造，故針對變更點進行說明，除此之外省略與先前說明共通的部分。如本實施形態般，配線根數為兩根的情況，只要非導電性線狀體21的根數為六根以上的話，可成為第一配線11與第二配線12不互相接觸的細繩。又，關於非導電性線狀體21的根數，是與第一實施形態相同。 (第二實施形態的作用效果) 根據本實施形態，除了前述第一實施形態的作用效果(1)、(3)及(4)以外，還可發揮下述作用效果(5)。 (5)第一配線11與第二配線12被編成絲狀，故該等之間隔非常窄。因此，即使是較少量的物質亦可感測，感測性能較高。 [第三實施形態] 接著，基於圖式來說明本發明的第三實施形態。本實施形態的感測器100B，如圖6所示般，具備第一配線11、第二配線12、一根非導電性線狀體21。而且，第一配線11及第二配線12，是分別在一根非導電性線狀體21捲繞成螺旋狀。在本實施形態，除了使第一配線11及第二配線12分別在一根非導電性線狀體21捲繞成螺旋狀以外，是與第一實施形態相同的構造，故針對變更點進行說明，除此之外省略與先前說明共通的部分。第一配線11與第二配線12，是分別在一根非導電性線狀體21捲繞成螺旋狀。且，在剖面觀看時，第一配線11及第二配線12，位於非導電性線狀體21之外周面的對角線上，故第一配線11與第二配線12不會互相接觸。非導電性線狀體21之剖面的形狀，並未特別限定，可為多角形狀、扁平形狀、橢圓形狀、圓形狀等，但就容易被導電性線狀體捲繞的觀點來看，以橢圓形狀、圓形狀為佳。非導電性線狀體21之剖面為圓形狀的情況時，非導電性線狀體21的直徑，是6μm以上3000μm以下為佳，15μm以上1500μm以下較佳，30μm以上900μm以下特佳。非導電性線狀體21之剖面為橢圓形狀的情況時，長徑是在與圓形狀之情況之非導電性線狀體21的直徑相同的範圍為佳。且，非導電性線狀體21之剖面為多角形狀的情況時，多角形之外接圓的直徑是在與圓形狀之情況之非導電性線狀體21的直徑相同的範圍為佳。且，就容易製作或性能展現性的觀點來看，非導電性線狀體21對第一配線11及第二配線12(導電性線狀體)的直徑比(非導電性線狀體/導電性線狀體)，以1/2以上為佳，1以上較佳，3以上特佳。非導電性線狀體21的直徑，是使用數位顯微鏡，觀察非導電性線狀體21的剖面，測量非導電性線狀體21的直徑。 (第三實施形態的作用效果) 根據本實施形態，除了前述第一實施形態的作用效果(1)、(3)及(4)以外，還可發揮下述作用效果(6)。 (6)第一配線11與第二配線12的間隔，與非導電性線狀體21的直徑相同，故非常窄。因此，即使是較少量的物質亦可感測，感測性能較高。 [第四實施形態]

the present invention will be described as an example based on the drawings. The present invention is not limited to the contents of the embodiments. In addition, in the drawings, some parts are shown enlarged or reduced for ease of explanation. (Sensor) The sensor 100 of the present embodiment includes the first wiring 11 , the second wiring 12 , and the non-conductive linear body 21 as shown in FIGS. 1 and 2 . Each of the first wiring 11 and the second wiring 12 includes a conductive linear body. The number of the non-conductive linear bodies 21 is six. The six non-conductive linear bodies 21 and the first wiring 11 and the second wiring 12 are wound to form a twisted wire. The first wiring 11 and the second wiring 12 are not in contact with each other. Moreover, when a substance is in contact between the first wiring 11 and the second wiring 12 , the substance can be sensed by the sensor 100 . The substance that can be sensed is not particularly limited as long as it is a fluid capable of electrically flowing. Specifically, a liquid, a gel-like fluid, etc. are mentioned. More specifically, water, urine, blood, etc. are mentioned. As a particularly preferable substance, a substance containing moisture is mentioned. Moreover, the sensor 100 is preferably a moisture sensor. (Wiring) The sensor 100 of the present embodiment may be provided with two or more wirings, and at least the first wiring 11 and the second wiring 12 may be provided. For example, other wirings (not shown) may be provided in addition to the first wirings 11 and the second wirings 12 . Each of the first wiring 11 and the second wiring 12 includes a conductive linear body. The first wiring 11 and the second wiring 12 may include a plurality of conductive linear bodies. In addition, the first wiring 11 and the second wiring 12 may contain other connecting materials (solder, conductive paint, etc.) or connecting members (connectors, etc.) other than the conductive linear body. (Conductive linear body) The conductive linear body used for the first wiring 11 and the second wiring 12 is not particularly limited as long as it has conductivity. Linear bodies of conductive filaments, etc. The conductive linear body may be a linear body (such as a linear body obtained by twisting a metal wire and a conductive thread) containing a metal wire and a conductive wire. In addition, in this specification, a linear body means a linear member. The length of the linear body is, for example, 1 cm or more. The form of the linear body is not particularly limited, and may be a single linear member or an aggregate of a plurality of linear members. The cross-sectional shape of the linear body can be changed into various shapes according to the shape of the linear body. Both the linear body containing metal wires and the linear body containing conductive filaments have high electrical conductivity, so if they are applied to the conductive linear body, it is easy to reduce the resistance of the first wiring 11 and the second wiring 12 . Examples of metal wires include wires containing the following materials: metals such as copper, aluminum, tungsten, iron, molybdenum, nickel, titanium, silver, and gold, or alloys containing two or more metals (stainless steel, carbon steel, etc. steel, brass, phosphor bronze, zirconium-copper alloy, beryllium-copper alloy, iron-nickel alloy, nickel-chromium alloy, nickel-titanium alloy, iron-chromium-aluminum alloy, Hester alloy and rhenium-tungsten alloy, etc.). In addition, the metal wire may be plated with tin, zinc, silver, nickel, chromium, nichrome, solder, or the like, or may be covered with a carbon material or a polymer to be described later. As a metal wire, the metal wire covered with a carbon material can also be mentioned. Metal wires, covered with carbon materials, can inhibit metal corrosion. Examples of the carbon material covering the metal wire include amorphous carbon (carbon black, activated carbon, hard carbon, soft carbon, mesoporous carbon, carbon fiber, etc.), graphite, fullerene, graphene, and nanocarbon tube etc. As the linear body containing the conductive yarn, a linear body formed of a single conductive yarn may be used, or a linear body formed by twisting a plurality of conductive yarns may be used. In addition, the conductive wire and the insulating wire may be twisted. The wire-shaped body containing conductive filaments has the advantage of being more flexible than the wire-shaped body containing metal wires and less likely to be broken. Examples of the conductive yarn include yarns containing conductive fibers (metal fibers, carbon fibers, ion-conductive polymer fibers, etc.), yarns containing conductive fine particles (carbon nanoparticle, etc.) Wires in which metals (copper, silver, nickel, etc.) are vapor-deposited, wires immersed in metal oxides, and the like. As the thread-shaped body containing conductive filaments, in particular, carbon nanoparticle particles preferably include: linear bodies of filaments containing carbon nanotubes (carbon nanotube filaments) (hereinafter also referred to as "nanotube filaments"). carbon tube-like body"). Carbon nanotubes, for example, from carbon nanotube bundles (a growth body formed by aligning carbon nanotubes on a substrate in a vertical direction with respect to the substrate, also called an "array") At the end, the carbon nanotubes are drawn into a sheet shape, and the drawn carbon nanotube sheets are bundled, and then the carbon nanotube bundles are wound. In this production method, a ribbon-shaped carbon nanotube linear body is obtained when a torsion force is not applied during winding, and a filamentary linear body is obtained when a torsion force is applied. Ribbon-shaped carbon nanotubes are linear bodies that do not have a structure in which a plurality of carbon nanotubes are twisted together. In addition, from the dispersion liquid of carbon nanotubes, carbon nanotubes can also be obtained by spinning or the like. The production of the carbon nanotube tubular body by spinning can be performed, for example, by the method disclosed in US Publication No. US2013/0251619 (Japanese Patent Laid-Open Publication No. 2011-253140). From the viewpoint of obtaining the uniformity of the diameter of the carbon nanotubes, it is better to use the filamentous carbon nanotubes, and the carbon nanotubes with higher purity can be obtained. It is preferable to obtain the filamentary carbon nanotubes by winding the carbon nanotube sheets. Carbon nanotubes are linear bodies in which two or more carbon nanotubes are intertwined. Carbon nanotubes are linear bodies containing carbon nanotubes, metals, conductive polymers, or conductive materials other than carbon nanotubes such as graphene (hereinafter also referred to as "composite linear bodies"). ) can also be used. The composite linear body can easily improve the electrical conductivity of the linear body while maintaining the above-mentioned characteristics of the carbon nanotube linear body. As the composite linear body, for example, taking the linear body containing carbon nanotubes and metal as an example, the following can be mentioned: (1) The carbon nanotubes are drawn into a sheet shape from the end of the carbon nanotube bundle, After the drawn carbon nanotube sheets are bundled, the bundle of carbon nanotubes is wound to obtain a carbon nanotube tubular body. The surface of the body is carried by vapor deposition, ion plating, sputtering, spraying, or wet plating to support the composite linear body of metal monomer or metal alloy; (2) make the bundle of carbon nanotubes A composite wire-shaped body formed by winding a wire-shaped body of a metal monomer or a wire-shaped body of a metal alloy or a composite wire-shaped body; (3) making the carbon nanotube wire-shaped body or composite wire-shaped body and the metal monomer A linear body or a metal alloy linear body or a composite linear body formed by winding a composite linear body, etc. In addition, in the composite linear body of (2), when the bundle of carbon nanotubes is wound, a metal may be supported on the carbon nanotubes as in the composite linear body of (1). In addition, the composite linear body of (3) is a composite linear body in which two linear bodies are braided, but as long as at least one metal single body linear body or metal alloy linear body or In the case of composite linear bodies, three or more of the carbon nanotube linear bodies, the linear bodies of metal monomers, the linear bodies of metal alloys, or the composite linear bodies may be knitted together. The metal of the composite linear body includes, for example, a single metal (gold, silver, copper, iron, aluminum, nickel, chromium, tin, zinc, etc.) and an alloy containing at least one of these single metals. (Copper-nickel-phosphorus alloy, copper-iron-phosphorus-zinc alloy, etc.). Among the conductive linear bodies, there are conductive linear bodies containing carbon nanotube filaments (in particular, conductive linear bodies containing only carbon nanotube filaments, or conductive linear bodies containing carbon nanotube filaments) A conductive linear body with a non-metallic conductive material) is preferred. For example, wires in which metals (copper, silver, nickel, etc.) are plated or vapor-deposited on the surface, and wires immersed in metal oxides, are easily cracked if the metal or metal oxide is stretched repeatedly, and the durability is low. At this point, the carbon nanotube tubular body has strong resistance to deflection, and the resistance value hardly changes even if it is repeatedly stretched and stretched. In addition, the carbon nanotubes have the advantage of high corrosion resistance. Here, the line resistance (resistivity) of the conductive linear body is preferably 5.0×10 ^-3 Ω/cm or more and 1.0×10 ³ Ω/cm or less, and preferably 1.0×10 ^-2 Ω/cm or more and 5.0×10 ² Ω /cm or less is preferred. In the case of a conductive linear body using a metal with high conductivity, the line resistance of the conductive linear body may be equal to or greater than the aforementioned lower limit. On the other hand, as long as the wire resistance of the conductive linear body is equal to or less than the upper limit, the resistance can be kept low even when the wiring path is long, and the wiring itself can be prevented from becoming a resistor and causing a load on the measuring device. The problem. The measurement of the wire resistance of the conductive linear body is as follows. First, silver paste was applied to both ends of the conductive linear body, and the resistance of the portion between the silver pastes was measured to obtain the resistance value (unit: Ω) of the conductive linear body. Then, the obtained resistance value was divided by the distance (cm) between the silver pastes, and the line resistance of the conductive linear body was calculated. The shape of the cross-section of the conductive linear body is not particularly limited, and may be a polygonal shape, a flat shape, an elliptical shape, a circular shape, or the like. Shape, round shape is preferred. When the cross section of the conductive linear body is circular, the diameter D (see FIG. 2 ) of the conductive linear body is preferably 2 μm or more and 1000 μm or less, and preferably 2 μm or more and 500 μm or less. Furthermore, from the viewpoint of flexibility and durability, the diameter D of the conductive linear body is preferably 5 μm or more and 300 μm or less, and more preferably 10 μm or more and 100 μm or less.

Furthermore, when the cross section of the conductive linear body is a polygonal shape, the diameter of the circle circumscribing the polygonal shape is preferably in the same range as the diameter D described above. The diameter D of the electroconductive linear body is obtained by observing the cross section of the electroconductive linear body using a digital microscope, measuring the diameter of the electroconductive linear body, and taking out the average value. (Non-conductive linear body) The non-conductive linear body 21 is not particularly limited as long as it is a linear body that does not have conductivity, and natural fibers, synthetic fibers, semi-synthetic fibers, and the like are exemplified. As a natural fiber, cotton, hemp, silk, wool, cashmere, etc. are mentioned. As synthetic fibers, polyester fibers, nylons, acrylic fibers, and the like can be mentioned. As semisynthetic fibers, rayon, modal, tencel, cupro, acetate fibers, diacetate fibers, triacetate fibers, and the like can be mentioned. As in the present embodiment, when the number of wires is two, as long as the number of non-conductive linear bodies 21 is six or more, the first wire 11 and the second wire 12 can be twisted without contacting each other. When the number of wirings is two, the number of the non-conductive linear bodies 21 is preferably six or more, preferably 10 or more, and particularly preferably 14 or more. Furthermore, from the viewpoint of making the sensor 100 more precise, the number of the non-conductive linear bodies 21 is preferably 30 or less. From the same viewpoint, the number of the non-conductive linear bodies 21 is preferably 3 times or more the number of wires, preferably 5 times or more the number of wires, and preferably 8 times or more than the number of wires. good. The shape of the cross-section of the non-conductive linear body 21 is not particularly limited, and may be a polygonal shape, a flat shape, an elliptical shape, a circular shape, or the like.

In addition, the diameter of the non-conductive linear body 21 is preferably 5 μm or more and 300 μm or less, and more preferably 10 μm or more and 100 μm or less, from the viewpoint of being easily entangled with the conductive linear body. When the cross section of the non-conductive linear body 21 is elliptical, the major diameter is preferably in the same range as the diameter of the non-conductive linear body 21 in the case of a circular shape. Furthermore, when the cross section of the non-conductive linear body 21 is polygonal, the diameter of the circle circumscribing the polygon is preferably in the same range as the diameter of the non-conductive linear body 21 in the case of the circular shape. In addition, from the viewpoint of easy entanglement with the conductive linear body or performance development, the diameter ratio of the non-conductive linear body 21 to the first wiring 11 and the second wiring 12 (conductive linear body) (non-conductive linear body) linear body/conductive linear body), preferably 1/5 or more and 5 or less, preferably 1/3 or more and 3 or less, more preferably 1/2 or more and 2 or less, and particularly preferably 1 or more and 3/2 or less.
