Exploiting Geometric Frustration in Coupled von Mises Trusses to Program Multifunctional Mechanical Metamaterials

open access: yesAdvanced Engineering Materials, EarlyView.
Mechanical metamaterials capable of compressive stiffness tunability, shape morphing, and post‐fabrication modularity. Herein, the 3D unit cell design is based on an assembly of bistable von Mises trusses that exhibit a switch in compressive stiffness and resting height from one stable state to the other.

Popliteus impingement after TKA may occur with well-sized prostheses [PDF]

open access: yes, 2016
To determine the mechanisms and extents of popliteus impingements before and after TKA and to investigate the influence of implant sizing. The hypotheses were that (1) popliteus impingements after TKA may occur at both the tibia and the femur, and (2 ...

A Standardized Method for Measuring Internal Lung Surface Area via Mouse Pneumonectomy and Prosthesis Implantation.

open access: yesJournal of Visualized Experiments, 2017
Pulmonary morphology, physiology, and respiratory functions change in both physiological and pathological conditions. Internal lung surface area (ISA), representing the gas-exchange capacity of the lung, is a critical criterion to assess respiratory ...

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

Shah′s Indian penile prosthesis placement after phallic reconstruction with radial forearm flap

open access: yesIndian Journal of Urology, 2008
We report a successful implantation of Indian penile prosthesis after total phallic reconstruction. The differential stiffness of the Shah penile prosthesis is felt to have less potential for erosion, the most common complication of rigid prosthetic ...
