Electromagnetic energy harvesting (EMEH) is an interesting way of extracting energy from vibrational sources, providing a viable power source for autonomous wireless sensor systems. Their implementation involves the elaboration of energy management circuits, which are specifically designed to enhance the voltage generated by the EMEH converter, bringing it to a level that meets the requirements for an efficient level of energy storage elements. In this paper, an EMEH converter with a dual-coil for different configurations as well as a study of phase-shifts from 0° to 180°, and input voltages between different harvesters output for parallel and series configurations using single and two rectifiers are presented. The output voltage for series configuration is higher than using single rectifier is higher than the parallel configuration until phase shift of 100

. For different input voltages the single rectifier is higher than the two rectifiers for series configuration. The simulation and experimental investigation of series configuration show that the error between them is 4.4 %, and 9.6 % for single rectifier, and two rectifers, respectively.

This study aims to identify the onset and progression of muscle fatigue during gripping exercises using surface electromyography (sEMG) signals. This research differs from previous studies in that it considers static and dynamic conditions, analyzing signals from three forearm muscles across a range of force levels. A novel approach combines dynamic and static data to comprehensively view muscle behavior. Muscle fatigue was assessed through feature extraction, including zero crossings (ZC), mean frequency (MNF), root mean square (RMS), and median frequency (MDF), with the MDF/RMS ratio introduced as a sensitive indicator of fatigue, especially at higher loads. These findings demonstrate the effectiveness of sEMG in monitoring fatigue and optimizing muscle performance, providing insights that inform the development of more effective training and rehabilitation strategies.
