“…Body movements impose dynamic loads that are convenient to be measured in implanted mechanical devices providing valuable information on the healing process and on the device varying environment [36,37]. Further, dynamic loads can be also taken to advantage in active tissue engineering strategies [6].…”

Electroactive materials can be taken to advantage for the development of sensors and actuators as well as for novel tissue engineering strategies. Composites based on poly(vinylidene fluoride), PVDF, have been evaluated with respect to their biological response. Cell viability and proliferation were performed in vitro both with Mesenchymal Stem Cells differentiated to osteoblasts and Human Fibroblast Foreskin 1. In vivo tests were also performed using 6-weekold C57Bl/6 mice. It was concluded that zeolite and clay composites are biocompatible materials promoting cell response and not showing in vivo pro-inflammatory effects which renders both of them attractive for biological applications and tissue engineering, opening interesting perspectives to development of scaffolds from these composites. Ferrite and silver nanoparticle composites decrease osteoblast cell viability and carbon nanotubes decrease fibroblast viability. Further, carbon nanotube composites result in a significant increase in local vascularization accompanied an increase of inflammatory markers after implantation.

“…Furthermore, local antimicrobial therapies inefficiently penetrate established biofilms, thereby triggering changes in quorum sensing and gene expression that further contribute to antimicrobial resistance 16 . In the case of PMMA, the porous, nondegradable carrier matrix itself may also serve as a substrate for bacterial adhesion and subsequent biofilm formation 17,18 . We previously tethered antimicrobial compounds to titanium implant surfaces to address the need to prevent bacterial adhesion and biofilm formation.…”

“…Their experimental results show approximately 40 % link efficiency at 2.5-MHz operating frequency and an output power of 100 mW. In [23], a medical relevance of the monitoring of deformation of implants is presented. It is a powerful tool to evaluate nursing and rehabilitation exercises for tracing dangerous overloads while anticipating implant failure and observing the healing process.…”

In wireless body area sensor networks (WBASNs), energy efficiency is an area of extreme significance. At first, we present a mathematical model for a non-invasive inductive link which is used to recharge the battery of an implanted biomedical device (pacemaker). Afterwards, we propose a distance-aware relaying energy-efficient (DARE) and mutual information-based DARE (MI-DARE) routing protocols for multihop mobility-aware body area sensor networks (MM-BASNs). Both the routing protocols and the non-invasive inductive link model are tested with the consideration of eight patients in a hospital unit under different topologies, where the vital signs of each patient are monitored through seven on-body sensors and an implanted pacemaker. To reduce energy consumption of the network, the sensors communicate with a sink via an on-body relay which is fixed on the chest of each patient. The behavior (static/mobile) and position of the sink are changed in each topology, and the impact of mobility due to postural changes of the patient(s) arms, legs, and head is also investigated. The MI-DARE protocol further prolongs the network lifetime by minimizing the number of transmissions. Simulation results show that the proposed techniques outperform contemporary schemes in terms of the selected performance metrics.
