This project shows the design and implementation of an electronic textile for continuous heart rate monitoring based on energy harvesting, divided into a sweater that incorporates the heart rate sensor along with the flexible solar panel for energy collection and a removable module that allows the display and sending of data. For the continuous measurement of beats per minute (bpm), the MAX30102 sensor was used, which uses the photoplethysmography method to detect the heart's pulsations based on the light reflected from the blood circulating in the blood vessels. These measurements are displayed on an oled display, located in the removable module on the chest, allowing easy viewing of data by the athlete. For data processing, the Arduino Lilypad USB microcontroller is used whose supply voltage can vary between 3.3 V and 5.5 V, for power supply to the microcontroller a flexible solar panel was used, which has a maximum output voltage of 7.9 V, this voltage is rectified by the MP1584EN reducer module whose output was adjusted so that when the solar panel delivers the maximum voltage of 7.9 V the module delivers a maximum of 5.35 V. To keep track of the data, they are sent to a database in Firebase, for which a SIM800L module using GSM/GPRS wireless technology was used. The sending of alerts for exceeding the maximum heart rate threshold is done by push notifications to the mobile device through the application developed for Android, which also allows access to the data log and to consult the connection and battery status of the clothing. Finally, bpm measurements are 98%, which is within the ANSI/AAMI EC13 standard, which establishes a percentage of up to ± 10% or ± 5bpm error.

The electromyograph uses an ESP32 microcontroller and the EMG AD8232 sensor that monitors the electrical signals coming from the muscles, the electrostimulator controls the time and frequency of the electrical pulses for rehabilitation. This information is sent to an Ubuntu Server in the Microsoft Azure cloud, which has a database to store this information and a web interface to visualize it. Taking into account the criteria of monitoring and rehabilitation applied to muscle injuries, as results, system operation tests were carried out with patients with mild muscle injuries, initial monitoring was performed and an average of 0.98 V was obtained and based on that, rehabilitation was carried out with a duration of approximately 12 sessions in an average of 10 minutes at an estimated frequency of 40 Hz, at the end of the last rehabilitation session the final monitoring was performed which indicated an improvement in the activity of the muscle with an average of 3.33 V. These results validate the efficiency of the system for the rehabilitation of muscle injuries present in amateur athletes of the DEPORMED Clinic. Keywords:
