Recovery system-based textile actuators

This paper presents a medical recovery system based on electrical stimuli transmitted through textile electrodes based on copper microparticles. The textile electrodes are connected to an electronic device capable of generating transcutaneous electrical nerve stimulation (TENS) using low-frequency (0–100 Hz) (diadynamic or interference) electrical currents. To evaluate the system, the current intensity, frequency and supply voltage were measured using different multimeters (Agilent Technologies U3606A and portable digital multimeter), and the signal was analysed. Depending on the intensity of the transcutaneous electrostimulation program, obtained by varying the electrical parameters, such as electrical voltage (U, mV), current intensity (I, mA) and frequency (f, Hz), it is possible that the patient feels pinches or vibration.
