Registration Date 29-10-2025 Organization Ternopil Ivan Puluj National Technical University popup.description1 Modern lower limb prosthetics are rapidly developing in response to the growing number of amputees, particularly in Ukraine, where this problem has become particularly acute in the context of a full-scale war. The loss of a lower limb leads not only to impaired motor function, but also to the loss of proprioceptive feedback - the sense of position, force of pressure and interaction with the supporting surface, which significantly reduces the efficiency and safety of movements. Classical mechanical prostheses do not provide adequate sensory feedback, which limits the user's adaptation, reduces his confidence in walking, complicates balance and increases energy expenditure during movement. Bionic systems, which are able to communicate two-way with the user's nervous system, open new horizons in medical rehabilitation, allowing to significantly improve the functionality of the artificial limb. The implementation of sensory feedback in lower limb prostheses involves registering mechanical loads, processing the corresponding signals, and transmitting tactile information back to the patient. This requires the creation of a comprehensive system that would include sensitive elements, protective devices, amplifier modules, actuators (e.g., vibration motors), as well as appropriate software and hardware. Solutions that combine piezoelectric sensors, energy-efficient amplifiers, and compact and wearable designs that can be integrated into shoes or insoles are particularly promising. The aim of this work is to develop a system for providing sensory feedback in a prosthetic lower limb that allows the user to receive information about the load on the prosthesis while walking. popup.nrat_date 2025-10-29 Close
