Final answer:
Computer-generated designs, dynamic response devices, and stored and released energy mechanisms are the key features of technologically advanced lower-limb prosthetic devices today.
Step-by-step explanation:
The most technologically advanced lower-limb prosthetic devices today can be described by the term computer-generated designs. These prosthetic devices are designed using computer technology and advanced engineering techniques to closely mimic the function of a normal foot.
They incorporate dynamic response devices that respond to the wearer's movements and provide a realistic sense of normal foot function. Additionally, they feature stored and released energy mechanisms that enhance the wearer's mobility and overall functionality.
