This paper introduces a flexiblearray Plantar sensor fabricated through the high-voltage electrospinning process of poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) , incorporating stannic oxide nanoparticles (SnO2NPS) and graphene (GR) composite nanofilm. The surface morphology, beta-phase crystal content, piezoelectric performance, composition, and structure of the composite piezoelectric films were evaluated using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, and a vibration platform. Experimental findings reveal that P(VDF-TrFE)/SnO2NPS/GR composite films containing 5% SnO2NPS and 0.1% GR exhibit superior open-circuit voltage and short-circuit current, measuring 22.43 V and 12.95 uA, respectively. These values are approximately 1.59 times and 1.34 times higher than those of the 5% P(VDF-TrFE) composite film and about 2.37 and 2.16 times higher than those of pure P(VDF-TrFE). A flexible piezoelectric sensor was fabricated using this composite film, and the mechanical properties and electrical impedance behavior of the sensor were investigated and analyzed. A multi-channel foot pressure collection and classification system was established based on this sensor, and a Parkinson's disease machine learning model for multi-channel foot pressure collection was investigated. Various machine learning models for Parkinson's disease were compared, and a fine K Nearest Neighbors (KNN) Parkinson's disease classification model with an accuracy of 97.1% was proposed. This offers a novel solution for Parkinson's disease diagnosis and holds significant reference value. [GRAPHICS] .

Pulse taking is one of the most important diagnostic methods in traditional Chinese medicine (TCM). It has been a long time since pulse taking was taken into studies. In this paper, we start with the introduction of the TCM pulse diagnostic apparatus. According to the application and requirement of the apparatus, we describe the characteristics and usage of the flexiblearray pressure sensor. We then review the current situation of its development at home and abroad. Finally, we analyze the advantages and defects of flexiblearray pressure sensor using in the pulse diagnostic apparatus and give some prospects.

In this study, a wireless sensor network (WSN) for flexible pH arraysensor has been developed by virtual software of National Instrument (NI) Laboratory Virtual Instrument Engineering Workbench (LabVIEW). The measurement data were received from measurement node and sent to a gateway connecting with computer through WSN. The WSN has been combined successfully with flexible pH arraysensor. And the sensitivity and linearity of the flexible pH arraysensor received through WSN are 53.39 mV/pH and 0.990 in pH concentrations between pH1 and pH13 at room temperate (25 degrees C), respectively. Therefore, the developed WSN can be applied to the flexible pH arraysensor practically.
