Summary: In this paper, a biomimetic optical skin (BOS) based on optical microfiber coupler neuron (OMCN) is proposed, which realizes multimodal tactile perception for the first time. BOS can sensitively detect temperature, contact force, vibration, and recognize the hardness and roughness of objects through human-like tactile sensing. Furthermore, the excellent repeatability and stability of BOS are investigated, laying the foundation for practical applications.

Summary: In this study, a reflective optical fiber sensor based on a PDMS-sealed optical microfiber coupler combined with a sagnac loop was proposed to achieve simultaneous measurement of temperature and pressure in seawater. The sensor showed improved sensitivity and structural stability compared to bare fiber sensors. Experimental results demonstrated the sensor's ability to demodulate temperature and pressure sensing simultaneously, with average errors of 1.61% and 5.02%, respectively. The sensor's compact structure, ease of fabrication, high sensitivity, fast response speed, and high stability make it comparable to existing TD sensors for marine environmental monitoring and ocean dynamics research.

Summary: This paper provides a comprehensive overview of the fabrication and implementation of graphene-PDMS-based composites for wearable sensing applications. Graphene is a significant nanomaterial known for its exceptional electrical, mechanical, and thermal properties, making it a preferred choice for multifunctional sensors. The use of polydimethylsiloxane (PDMS), a commonly used polymer in biomedical applications, in conjunction with graphene as a substrate or polymer matrix has been emphasized. The paper also highlights the various electrochemical and strain-sensing applications of these graphene/PDMS-based sensors in detecting physiological signals and parameters of the human body. The challenges and future perspectives of these wearable sensors are also discussed.
