Prosthetics serve as artificial replacements for lost or impaired limbs or body parts. Lower limb prosthetics specifically aim to restore mobility and support body weight during activities like standing and walking. Research demonstrates that incorporating biofeedback into gait training can enhance movement patterns effectively during rehabilitation. This paper introduces an assistive device designed to aid individuals with transfemoral amputations. The device employs vibrotactile stimulation to provide sensory support during prosthesis usage. During bench experiments, the gadged produces a vibration acceleration of 0.48 m/s2, which could cause some discomfort to the user, depending on their sensitivity and tolerance. Hence, in order to integrate the device into the patient's prosthesis, adjustments to the electronic circuit are required to directly evaluate the comfort of the vibration in real-life usage scenarios.
