Description
生体を構成する組織には圧電性を有するものが多い。例えば、人体を構成するコラーゲンは、タンパク質の一種であり、血管、真皮、じん帯、健、骨、または軟骨等に多く含まれている。コラーゲンは、圧電体であり、コラーゲンが配向した組織は非常に大きな圧電性を示す場合がある。骨の圧電性については既に多くの報告がなされている(例えば、深田栄一,生体高分子の圧電気、高分子Vol.16(1967)No.9 p795-800等を参照)。したがって、圧電糸1または圧電糸2を備えた布により電場が生じ、該電場が交番するか、または該電場の強度が変化すると、生体の圧電体は、逆圧電効果によって振動を生じる。圧電糸1および/または圧電糸2によって生じる交番電場、あるいは電場強度の変化により、生体の一部、例えば毛細血管や真皮に微小な振動が加えられ、その部分の血流の改善を促すことができる。これにより皮膚疾患や傷等の治癒が促される可能性がある。したがって、圧電糸は、生体作用圧電糸として機能する。複数の圧電糸と導電糸を用いて編物や織物にし、これに変位が加わった事をセンシングするトランスデューサーがWO2015/159832に公開されている。この場合、導電糸はすべて検知回路に接続されており、一本の圧電糸に対して必ず対の導電糸が存在する。WO2015/159832では、圧電糸に電荷が発生した時、導電糸を電子が移動し、発生した電荷を即座に中和する。WO2015/159832では、この電子の移動による電流を検知回路が捉えて信号として出力する。従ってこの場合、発生した電位は即座にキャンセルされるので、圧電糸と導電糸との間、および圧電糸と圧電糸との間に強い電場が形成される事がなく、治癒効果は発揮されない。
上述したように、圧電糸1は、外力が係った場合に、負の電荷を生じる。圧電糸2は、外力が係った場合に、正の電荷を生じる。そのため、圧電糸1は、正の電荷を有する物質(例えば花粉等の粒子)を吸着する性質を有し、圧電糸2は、負の電荷を有する物質(例えば黄砂等の有害物質等)を吸着する。したがって、圧電糸1または圧電糸2を備えた布は、例えばマスク等の医療用品に適用した場合に、花粉または黄砂等の微粒子を吸着することができる。複数の圧電糸と導電糸を用いて編物や織物にし、これに変位が加わった事をセンシングするトランスデューサーがWO2015/159832に公開されている。この場合、導電糸はすべて検知回路に接続されており、一本の圧電糸に対して必ず対の導電糸が存在する。WO2015/159832では、圧電糸に電荷が発生した時、導電糸を電子が移動し、発生した電荷を即座に中和する。WO2015/159832では、この電子の移動による電流を検知回路が捉えて信号として出力する。従ってこの場合、発生した電位は即座にキャンセルされるので、圧電糸と導電糸との間、および圧電糸と圧電糸との間に強い電場が形成される事がなく、吸着効果は発揮されない。
