Abstract

In this study, a multifunctional device was developed using the organic piezoelectric material polyvinylidene fluoride (PVDF) to detect mechanical operations. This device utilizes a mechanism in which the resonance of the element structure is excited and detected using PVDF. This enabled the proposal of a device principle that can allow detection of various physical quantities, such as differential pressure and acceleration. The device can detect low pressures of up to 1.5 kPa with a sensitivity of −0.19 Hz/Pa. Additionally, it can measure acceleration with output linearity and cross-axis sensitivity. This device is advantageous because it can evaluate both pressure and acceleration using a common sensor structure and measurement methods, and it can be manufactured at room temperature using inexpensive materials. It holds potential for applications in the maintenance of various industrial machinery and monitoring of natural disasters.

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.
