Abstract
This work proposes a wireless instrumented insole for monitoring plantar pressure (PP) during human locomotion. The insole is composed of two elements. The first is a mold manufactured with thermoplastic polyurethane using tridimensional printing techniques. The second one is a soft cover fabricated with a liquid polymer Ecoflex™ 00–30 from Smooth-On. The insole considers a microcontroller Arduino Nano and 24 force-sensing resistors located in ten anatomic regions of the foot with a sampling frequency of 70 Hz. The device sends the data through wireless communication based on a Bluetooth module to a graphical user interface in a computer where the data is received, displayed, and stored. A test was carried out with ten healthy volunteers (five men and five women) to validate the PP measured with the device. The data obtained were analyzed and compared with the literature, considering relevant characteristics in the PP analysis.
期刊介绍：
Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies.
The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
