Накратко на български

Биосъвместимите полимери с електрически заряд се изследват за създаване на гъвкави сензори и задвижващи механизми, подобни на биологичните структури. Те могат да помогнат за разработването на по-безопасни импланти, умни протези и носима електроника.

Development of biocompatible ionic electromechanically active polymer actuator/sensor

Bioinspired devices and soft robotics are of great interest in nowadays science. Technological development towards biomimetic systems requires replacement for traditional actuators (thermochemical motors, electromagnetic drivers and hydraulic or pneumatic machines). Classical engineering uses joined rigid parts, but biological structures are flexible and generate motion without rigid mechanical constituents. Moreover, in biological systems the materials often fulfil different roles at the same time, increasing efficiency. Electroactive polymers (EAPs) possess several biomimetic characteristics. It is a large family of different materials that response to external electrical stimulation with change in size or shape. The current project focused on ionic electromechanically active polymers (IEAP). Potential applications for IEAPs include implantable or disposable biomedical devices, smart prosthesis, soft haptic devices and wearable electronics. The mentioned applications require biocompatibility from the materials, which has remained challenging during decades on research in EAPs. The aim of the current project was to develop biocompatible IEAPs functioning as actuators/sensors applicable in smart medical devices. A typical IEAP is a soft thin laminate composed of a microporous ion-permeable polymer membrane placed between electrodes with a high specific surface area consisting of either metals, conductive polymers or carbon materials. The system is swollen by an appropriate electrolyte, for example ionic liquid (IL). IEAPs can work as actuators or as motion sensors: transducing between electric current and mechanical deformation. To achieve biocompatible IEAPs, all the components need to be low toxicity and safe to use. There are suitable candidates for electrode and membrane materials but the key towards biocompatible IEAPs is non-toxic ILs working as electrolytes. The research carried out towards the aim had two objectives. First, to develop low toxicity ILs to be applied as electrolytes in the IEAPs. Choline ILs and their mixture were proposed as safer alternative to the rather toxic imidazolium ILs currently used. Secondly, to prepare and characterize biocompatible IEAPs consisting of biopolymer membrane, polypyrrole (PPy) electrodes and the developed biofriendly electrolytes.

Цел на проекта

Bioinspired devices and soft robotics are of great interest in nowadays science and technology. Technological development towards biomimetic systems requires replacement of traditional actuators. Most of the industrial robots consist of joined rigid parts, but in nature biological structures are flexible and generate motion without motors and other rigid mechanical constituents. Electromechanically active polymers (EAPs) are potential materials for preparation of biomimetic devices. These stimuli responsive materials have been in the focus of intense research already for decades and have gone through significant development during this time in terms of work output and operation voltage. However, proposed applications for EAPs in biotechnology and biomedical engineering require biocompatible materials. Preparation of EAP actuators/sensors from entirely biocompatible materials is still remained an unattained challenge and will be the aim of the current project. Developed materials have high commercialization potential and influence to our everyday life due to applications in medical devices and consumers electronics (smart prosthesis, soft haptic devices, wearable electronics). Therefore the project is in accordance with European Research Area and Innovation Union Flagship Initiative principles to get more innovation out of the research. Successful accomplishment of the project goals enhance the experienced researcher's career prospects by complementing her experiences in organic chemistry with new knowledge in electrochemisty, toxicology and computational simulations.
