摘要

热声效应探测仪在实现导电膜的无振动发声方面具有很大的潜力。然而，制造具有高稳定性的可拉伸导电薄膜仍然是一个挑战。在本文中，利用导电垂直石墨烯（VGr）薄膜开发了一种可拉伸热声测深仪。在100%的最大拉伸应变下，VGr薄膜的电阻仅增加了23%。热声测深仪可产生1-22 kHz频率范围内的声音，可稳定输出50%张应变下的声波，声压级大于60 dB。这项工作为制造可穿戴薄膜测深仪铺平了道路。

A stretchable thermoacoustic sounder based on vertical graphene

Thermoacoustic effect sounders have great potential in achieving the vibration-free sound generation of conductive films. However, the fabrication of stretchable conductive films with high stability remains a challenge. In this paper, a stretchable thermoacoustic sounder has been developed using a conductive vertical graphene (VGr) film. At 100% maximum tensile strain, the resistance of the VGr film only increased by 23%. The thermoacoustic sounder can produce sound in the frequency range of 1–22 kHz and can stably output sound waves under 50% tensile strain with the sound pressure level of greater than 60 dB. The work paves a way in fabricating wearable thin-film sounders.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
