Protótipo de um dinamômetro de baixo custo para medição de força muscular

Abstract

: In the medical field, the use of accurate measuring instruments to determine better and faster diagnoses has been one of the great advances in technology. However, these advances generally when they happen, have a very high cost. Thus, this work deals with the creation of a prototype for the measurement of muscular strength, intended for implementation in the physiotherapeutic area, using low cost resources and easily accessible material, from load cells and with a maximum capacity of 100 kilograms, being thus its use in different members of the body is possible. The construction of the prototype is shown from its conception, dimensioning of the sensors used, until its assembly. The device is measured experimentally, and results of its calibration are obtained using weights with known values. The prototype features an embedded system, which records all measurements made, in addition to having an easy-to-use user interface. The device was made using Arduino, it was simulated and built following the dimensioned steps. After the construction of the prototype, several measures were taken to prove the feasibility of its use in the medical field, thus showing its possible use as a medical instrument.
