These systems are designed for physiotherapy purposes, with NanoStim focusing on the treatment of knee pathologies and NanoID on balance control. The goal of this work is to create a compact electrical stimulation driver with low processing consumption capable of inducing muscle contractions in a wide range of applications. The proposed solution involves the development of two transformer-based stimulation drivers, each controlled by a microcontroller and a mobile application. These drivers are based on distinct transformer models, each tailored to produce muscle contractions through the application of electrical pulses and are designed to meet the requirements for integration into wearable systems. Both alternatives underwent testing and validation with volunteers, and the collected data was analyzed to determine the optimal circuit alternative for implementation in both wearable systems.engElectrical stimulationFunctional electrical stimulationElectrical stimulation circuitWearable systemmaster thesis203474759
