| Outline of Final Research Achievements |
Biodegradable implants are gaining attention as devices that do not require removal surgery because they degrade in the body over time. This study aims to construct a force testing system capable of real-time monitoring of the mechanical strength associated with degradability, and to establish the elemental technology for such a system. First-principles calculations were used to design the composition of biodegradable magnesium and zinc alloys to optimize their strength and degradability. Toughened wires were fabricated by forming heterogeneous microstructures through plastic working. Finally, a method to form biodegradable microforce sensors was established and implemented on the implant surface.
