To address the communication barriers between deaf-mute individuals and the hearing population, this paper proposes a gesture recognition scheme based on a stretchable piezoresistive sensor (SPTS) composed of silver-coated glass microspheres and solid rubber (Ag@GMs/SR), integrated with machine learning algorithms. The sensor uses solid rubber as a flexible matrix, with silver-coated glass microspheres attached onto its surface as conductive fillers via an impregnation-drying method, providing high sensitivity, a wide stretchable range, and excellent environmental stability. The sensor can be sewn into a glove to achieve multi-channel hand motion capture. The collected signals are amplified, filtered, and transmitted to a host computer via Bluetooth. A sliding window averaging method combined with a differential thresholding technique is used to suppress environmental interference. Principal component analysis (PCA) is employed for dimensionality reduction, and a support vector machine (SVM) with a radial basis function kernel is adopted for gesture classification. Experimental results demonstrate that the proposed system achieves an average recognition rate of 96.3% for 30 common sign language gestures, with a response time of approximately 128 ms. Under fluctuating temperature and humidity conditions, the recognition rate varies by less than 2%. This provides a feasible wearable solution for real-time and effective communication between deaf-mute and hearing individuals. %K 压阻传感器， %K 镀银玻璃微球， %K 手势识别， %K 支持向量机， %K 主成分分析
