High sensor response to reducing gases in exhaled breath such as ethanol, acetone, and isoprene was obtained, confirming the effect of the crystal face of the pyramidal zinc oxide particles on gas sensor performance. The loading effect of noble metal nanoparticles to the zinc oxide particles on the sensor properties was also investigated, and the effect on sensitivity improvement and gas selectivity was confirmed. The effect of water vapor was also investigated, and it was shown that the sensor can detect gases with concentrations equivalent to exhaled breath even at high humidity. The effect of gold particles on gas selectivity for isoprene gas was also demonstrated."}]},{"type":"significance_of_research_achievement","notation":[{"@language":"ja","@value":"近年のガスセンサには、従来の安全・安心に貢献する警報器だけでなく、健康・環境の分野や、より快適な暮らしや持続可能な社会の構築に期待が高まっており、小型化、省エネ化、モバイル・ウェアラブル機器への実装化が求められている。本研究は、材料の基礎的な理解と、その機能を最大限に引き出した高性能化への技術に関するもので、デバイス応用への課題の解決に貢献できると考えている。"}]}],"researcher":[{"@id":"https://cir.nii.ac.jp/crid/1420282801203038464","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"90552480"},{"@type":"NRID","@value":"1000090552480"},{"@type":"NRID","@value":"9000391873056"},{"@type":"NRID","@value":"9000399344016"},{"@type":"NRID","@value":"9000018569873"},{"@type":"NRID","@value":"9000024959153"},{"@type":"NRID","@value":"9000391881665"},{"@type":"NRID","@value":"9000324997676"},{"@type":"NRID","@value":"9000024967069"},{"@type":"NRID","@value":"9000018788756"},{"@type":"NRID","@value":"9000257963089"},{"@type":"NRID","@value":"9000257963172"},{"@type":"NRID","@value":"9000368411095"},{"@type":"NRID","@value":"9000014159108"},{"@type":"NRID","@value":"9000020457740"},{"@type":"NRID","@value":"9000402003168"},{"@type":"NRID","@value":"9000400162615"},{"@type":"NRID","@value":"9000368411357"},{"@type":"NRID","@value":"9000345349510"},{"@type":"NRID","@value":"9000401989200"},{"@type":"NRID","@value":"9000020414301"},{"@type":"NRID","@value":"9000020457942"},{"@type":"NRID","@value":"9000324997706"},{"@type":"NRID","@value":"9000243886924"},{"@type":"NRID","@value":"9000018655906"},{"@type":"NRID","@value":"9000402010196"},{"@type":"NRID","@value":"9000401570498"},{"@type":"NRID","@value":"9000402928901"},{"@type":"NRID","@value":"9000403287377"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/kenwatanabe-ku2016"}],"foaf:name":[{"@language":"ja","@value":"渡邉
