Abstract
This report shows the design process of developing a more comfortable transtibial prosthetic socket by introducing focal vibration therapy as a method for residual limb recovery. Rather than focusing only on the main factors of socket discomfort (pressure and volume change), the project explores comfort through a rehabilitation perspective. A concept was developed based on user research, market analysis, and anatomical insights. Voice coil actuators were selected as the most suitable option for focal vibration, and a simplified prototype was built to demonstrate the motor placement. With a strong emphasis on user needs, the project aims to enhance daily comfort in lower-limb prosthetic sockets.
