Highly Flexible Graphene-Film-Based Rectenna for Wireless Energy Harvesting

引用

Energy & Environmental Materials 2024年第2期7卷 324-329页

作者： Jingwei Zhang Yuchao wang rongguo Song Zongkui Kou Daping He Hubei Engineering Research Center of RF-Microwave Technology and Application School of Science Wuhan University of Technology Sanya Science and Education Innovation Park of Wuhan University of Technology State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology

Herein, we report the design, fabrication, and performance of two wireless energy harvesting devices based on highly flexible graphene macroscopic films（FGMFs）. We first demonstrate that benefiting from the high conductivity of up to 1 × 10～6S m-1and good resistive stability of FGMFs even under extensive bending, the FGMFs-based rectifying circuit（GRC）exhibits good flexibility and RF-to-DC efficiency of 53% at 2.1 GHz. Moreover,we further expand the application of FGMFs to a flexible wideband monopole rectenna and a 2.45 GHz wearable rectenna for harvesting wireless energy. The wideband rectenna at various bending conditions produces a maximum conversion efficiency of 52%, 46%, and 44% at the 5th Generation（5G） 2.1 GHz, Industrial Long-Term Evolution（LTE） 2.3 GHz, and Scientific Medical（ISM） 2.45 GHz, respectively. A 2.45 GHz GRC is optimized and integrated with an AMC-backed wearable antenna. The proposed 2.45 GHz wearable rectenna shows a maximum conversion efficiency of 55.7%. All the results indicate that the highly flexible graphene-film-based rectennas have great potential as a wireless power supplier for smart Internet of Things（Io T） applications.

中医骨伤科学是中医学教学体系中的主干课程,具有很强的实践性。课程要求学生在深入理解中医基础理论基础上,掌握常见骨伤科疾病的诊断和治疗。随着高等教育教学改革的深入及社会的高速发展,传统的教学模式已无法满足复合型人才的培养需求。基于教学大纲要求和课程特点,在教学中运用虚拟仿真技术,能生动直观地帮助学生补充解剖学知识,增强对损伤病因病机和局部病理变化的理解,有助于教学质量提升。目前虚拟仿真试验的教学项目仍处于探索阶段。此文基于现状与存在的问题,积极探索中医药院校中医骨伤科学虚拟仿真试验教学项目的建设思路,以期优化中医骨伤科学的教学模式,提升相关教育教学平台的建设水平。

马祖道一约于开元末年抵达闽北,“肇化”建阳佛迹岭。天宝五至八年间,移锡江西抚州西里山。此二处弘法虽有影响,属道一弘法的开拓时期。广德元年至大历元年间,往虔州龚公山建立“清净梵场”,为其弘法的发展时期。大历七年秋至八年九月间,移锡洪州,确立以开元寺为弘法的中心,为其弘法的繁盛时期,其法席之盛为南方禅宗史上空前。文章对宋僧传本传以及智藏、超岸的记载、《全唐文》本的权德舆所撰塔铭作了辨误,并指出权德舆塔铭记载的疏漏;对有关道一在江西行迹研究的观点提出不同的看法。

泉州开元慈儿院是圆瑛法师亲自创办的慈善性质的亦教亦养的初等教育。慈儿院招生对象、人数、教学与师资选聘等都体现了圆瑛法师的办学思想。为了使慈儿院能长期延续下去,圆瑛法师提出设立“常年基金”,为此,他不但呼吁社会各方伸出援助之手,还不畏惊涛骇浪之险,远渡重洋赴南洋募捐。兴办慈善性质的教育实体是近代出现的新事物,是当时中国佛教所面临的新课题,圆瑛法师在兴办慈善教育事业方面所作的努力,某种意义上说,是对佛教理论与实践的发展。

义存出家的玉涧寺在唐莆田县城西北,铃木哲雄说的'城西三里'为明后期兴化府城与'玉涧寺址'的距离。铃木认为'芙蓉院'创于唐太和七年,然其使用资料、论证等存在问题。会昌法难后,义存于大中四年在幽州受戒,铃木认为'幽州未得戒',其所据资料属伪作。义存于法难前参盐官,法难后参杭州大慈山(今西湖虎跑寺)寰中、江西仰山慧寂,'九上洞山'参良价,未'三到投子'。义存于咸通二年参宣鉴而承其旨,咸通六年秋冬间,别宣鉴,与全豁游方,途中'鹅山成道',而非'鳌山成道'。义存于咸通七年回福州芙蓉山,未在建安结庵。以考古出土的唐翁承赞《闽王墓志》订正黄滔《真觉大师碑铭》的错讹。对《雪峰志》、《年谱》、蓝文卿'遗嘱'作辨误。

《续高僧传·菩提达摩传》中的“宋境”一词有“时间+空间”的含义,意即“刘宋的境内”,并非孙述圻所说是泛指五到六世纪的“中国南方政权”的辖地。菩提达摩的于刘宋明帝至顺帝年间取海路来华,抵达“宋境南越”,“菩提达摩是否谒永宁寺”是确定《续僧传》与《伽蓝记》所载的“菩提达摩”是否为同一人的重要逻辑环节,胡适没有作这一环节的“求证”。考古资料揭示,道宣对永宁寺的记载有失实;文献考证表明,道宣撰《续高僧传》时,依据《洛阳伽蓝记》一书,但删去菩提达摩谒永宁寺一事,证明了二书所载的“菩提达摩”同为一人。菩提达摩大致于神龟元年（518）至永安三年（530）之间谒永宁寺。
