Opis:: The following paper is a reflection on the advisability of using auxetic structures in medical devices. For this purpose, a model of a skull implant was designed. This implant could be used for cranioplasty of bone defects after neurosurgical procedures. The implant is made of a titanium alloy and has an auxetic "double arrow" structure. The behavior of the implant was investigated in two cases, under the influence of increased intracranial pressure and impact of an external force. The calculations were made with the finite element method implemented in the SolidWorks 2020 program. Moreover, the natural frequency of the structure was examined in the Comsol Multiphysics program.

Opis:: This article presents the simulation of a prosthetic socket with an auxetic structure under typical loading cases. The designed model of prosthetic socket is dedicated to patients who have undergone transfemoral amputation and consists of four elements, among which can be distinguished an inner lining, a shock absorbing element, component with a honeycomb re-entrant structure, which has a negative Poisson's ratio an outer shell. The prosthetic socket was analysed by means of the finite element method. The simulations were used to evaluate the strength of the design and to check whether it is possible to avoid a problem of changing the circumference of the patient's stump, thanks to the use of an auxetic structure in the socket.
