Laser Direct‐Write Sensors on Carbon‐Fiber‐Reinforced Poly‐Ether–Ether–Ketone for Smart Orthopedic Implants (Adv. Sci. 11/2022)

Laser Direct‐Write Technique Carbon‐fiber‐reinforced polyetheretherketone (CFR‐PEEK) is a rising material of orthopedic implants with superior biocompatibility and in vivo stability. In article number 2105499 by Haiyan Zhao, Zhe Zhao, Xining Zang, and co‐workers, a laser direct‐write method with multiple degrees of freedom is adopted to fabricate strain sensors on complex surfaces of CFR‐PEEK parts. Wireless signal transmission is deployed by a Bluetooth module, allowing real‐time monitoring of implant loading progressing and personalized post‐surgery care. [Image: see text]
