Modern research focuses on natural, green, and sustainable materials that can be used to replace conventional materials. Because of their beneficial qualities, natural fibre composites are being thoroughly researched. This the development a flax reinforced with phenol-formaldehyde resin hybridization ramie through vacuum infusion process. Eight different sequences were fabricated using core–sheath structure mechanically characterized as per ASTM standards. The fabrication technique influences adhesion matrix reinforcement. results also reveal composite having sheath layer core delivers good mechanical characteristics compared vice versa. laminate H exhibited highest properties among all eight laminates produced for this study. It tensile strength 54 MPa, modulus 0.98 Gpa, elongation 7.1%, flexural 143 Mpa, compressive 63.65 Mpa. stress strain curves revealed ductile behaviour before failing during test test, respectively. stacking sequence influenced by it its counterparts. A morphological study was carried out analyse failure surfaces. Morphological analysis few defects in after tests. developed better than commercial available market, which lightweight structural applications.

Recent Advances in Self-Powered Wearable Sensors Based on Piezoelectric and Triboelectric Nanogenerators

Biosensors, Journal Year: 2022, Volume and Issue: 13(1), P. 37 - 37

Published: Dec. 27, 2022

Early clinical diagnosis and treatment of disease rely heavily on measuring the many various types medical information that are scattered throughout body. Continuous accurate monitoring human body is required in order to identify abnormal signals locate factors contribute their occurrence a timely manner. In fulfill this requirement, variety battery-free self-powered methods collecting have been developed. For purpose health system, paper presents smart wearable sensors based triboelectric nanogenerators (TENG) piezoelectric (PENG), as well hybrid combine (PTNG). Following presentation PENG TENG principles, summary discussion most current developments with purposes, structural designs, electric performances follows. Wearable generate own electricity crucial not only for proper development children patients unique conditions, but maintaining checks wellbeing elderly those who recently recovered from illness, administering any necessary care. This work sought do two things at once: provide perspectives monitoring, open up new avenues analysis long-distance biological movement status.
