Talk Prof. Derbel - martedì 30 Gennaio

Talk n.1 (30/01/2024 11:00-11.45) – BUILDING 14 – ROOM D31

Advancements in novel measurement systems, materials, and wireless power transfer designed for biomedical applications

Abstract: In the first step of this talk, I will present the University of Sfax, then the National Engineering School of Sfax, and then the Control and Energy Management Laboratory. The second step consists to present our project TIRAM which is entitled « Teleassistance for people with respiratory difficulties using ventilation adapted to thoracic tomographic bioimpedance measurements ». The aim of this project is to develop a system to assist people suffering from acute or chronic respiratory insufficiency. The system consists of an artificial respirator, a non-invasive system for tomographic measurement of the electrical impedance of the lungs and a digital platform that will provide real-time remote diagnosis and collaborative remote expertise. The third part is dedicated to the wireless power transfer. In fact, over the last decades, the use of wireless power transfer technology has grown dramatically, in several applications, such as electric cars, medical implants, drones, Internet of things and smart phones which are examples of the main applications employing this very convenient powering alternative. I will focus on the design and the optimization of a planar circular coil in order to reach the maximum of its quality factor. The fourth part discusses the control of resorbable bioactive glass (BaG) dissolution to suit different patient age groups. This consists to develop new Biocompatible and Bioresorbable bioactive Glass (BaG) adaptable to different medical requirements from a controlled chemical composition according to the age, sex and patient health statement. This product is dedicated to several applications, such as the repairing of bone fractures.

On the Control of Robotic Systems for Rehabilitation

Abstract: Rehabilitation plays a crucial role in the holistic care and development of children with cerebral palsy (CP) which is a neurological disorder that affects movement and posture, often leading to challenges in daily activities and overall functionality. Early intervention through rehabilitation services is imperative for children with CP to maximize their potential and enhance their quality of life. Rehabilitative therapies, such as physical therapy, occupational therapy, and speech therapy, are tailored to address specific motor, cognitive, and communication difficulties associated with CP. These interventions aim to improve muscle strength, coordination, and flexibility, allowing children to gain better control over their movements. Our objective is the control of robotic systems for rehabilitation of children with cerebral palsy aiming to enhance motor function, improve coordination, and promote overall well-being. Robotic rehabilitation systems offer the advantage of providing repetitive and tailored exercises, ensuring targeted therapy and individualized progress tracking. Here are key aspects of the control strategies for robotic systems used in the rehabilitation of kids with cerebral palsy. We focus on a robust control approach. The use of an adaptive procedure in order to apply this controllers for kids aged from 18 months to 13 years. Then we consider adaptive PID controllers and adaptive sliding mode controllers.
