Hierarchically structured porous natural dielectric layer for sustainable pressure sensing, gesture monitoring, and detecting spatial pressure distribution
Flexible pressure sensors are essential in intelligent skins, healthcare monitoring systems, and soft robotics to bridge mechanical movements and electrical signals. Conventional pressure sensors, however, have a variety of challenges, including a complex fabrication method, increased cost, and biocompatibility issues. This work presents a novel bio-friendly, hierarchically structured porous natural dielectric material based capacitive pressure sensor featuring a maximum sensitivity of 0.0572 kPa−1. The proposed pressure sensor uses a biofilm with a typically arranged honeycomb structure as a dielectric layer sandwiched between the Aluminum (Al) electrodes and incorporates polydimethylsiloxane (PDMS) encapsulation. With a 1.44 cm2 sensing area, the device exhibits a response time (Tres) of 250 ms and a recovery time (Trec) of 156 ms, functioning within a capacitive pressure sensing range of 0–110 kPa. This device monitors various human activities and stimuli and accurately detects pressure distribution and gesture recognition.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
