Sensores flexíveis resistivos para reprodução de movimentos da mãos

Abstract

This project aims to study and prototype a flexible resistive sensor, integrated with a liquid metal alloy, and to implement a methodology for computational vectorization of the signals collected. Flexible resistive sensors are notorious for their adaptability in diverse applications, ranging from biomedical devices to sensors for monitoring human movements in wearables. The presence of the liquid metal alloy enhances the versatility of these sensors. Characterization is essential in order to understand the sensor's behaviour under various operating conditions, guaranteeing the accuracy of measurements. Computational vectorization will enable effective analysis and the extraction of relevant information from the raw data. During the tests, it was observed that the resistance of the sensor increases with stretching, which is compatible with the theory of electrical resistance in materials. This project contributes to advancing the use of these sensors by providing characterization guidelines and specialized computational tools for processing and interpreting the data, especially in the context of applications in wearables aimed at monitoring finger movements.
