The project involves the development of an experimental model of electromagnetically actuated micropumps for applications in the field of microfluidics. The work plan proposed in this project is focused on the formulation of magnetic pastes / inks for screen-printing technology, so that these separate components could be integrated in the fabrication of micropumps for further exploitations in BioMEMS devices. In order to reach the project scope, five specific objectives (SO) were considered:
SO1. To obtain a composite material with exceptional magnetic responsive features mainly characterized by a structural homogeneity.
SO2. Establishing the relevant characteristics of magnetic ink/paste that can satisfy the requirements of the deposition technology.
SO3. Laboratory validation of a technology which aims to obtain a magnetic ink/paste to be used as coatings for BioMEMS devices.
SO4. Evaluation and functionality of the demonstrator model by integrating the technology for obtaining magnetic inks/pastes with deposition techniques used in microelectronic devices.
SO5. Consolidation and protection of intellectual property rights regarding the technologies elaborated within the project.
SO6. An efficient collaboration and project management to diminish the risks of implementation and to avoid delays.
The project approaches an experimental and demonstrative research seeking the development of novel magnetic inks/pastes to be used for screen-coating (printing) of micropumps and is expected to achieve a directional movement in a controlled electromagnetic external field. In view of implementing the demonstrator model, the project begins from a conceptual level which consists in the design of a composite type ink/paste material, capable of responding to a magnetic field (TRL 2). The expertise of the consortium as presented in the section devoted to preliminary results is a proof of the TRL2 level. At the next level, the proof-of-concept will be validated by initiation of the active process of research and development involving preliminary laboratory studies, which aim to confirm the analytical predictions of separate components (TRL3). Thus, the obtained data will be integrated in order to identify the most suitable material’s formula and deposition technique for assuring targeted application. The final stage of the current project is to develop an EM actuated micropump based on implementing these innovative technological components which will be validated by laboratory studies (TLR4). By achieving these levels of Technology Readiness, the current project will represent a step further towards the development of new magnetic micropumps which are expected to increase their use in applications like (bio)chemical sensing or drug delivery.
Research activities are carried out in effective collaboration between University POLITEHNICA of Bucharest and NANOM MEMS SRL and involves preliminary studies to obtain magnetic nanoparticles; formulation of magnetic pastes/inks with predetermined characteristics; initiation of magnetic pastes/inks depositions on specific substrates used in BioMEMS devices, followed by complex characterizations regarding physico-chemical properties, including electrical ones. Also, the functionality of the developed films will be tested at laboratory level to prove their actuation characteristics. To optimize the performances of the formulations of magnetic inks/pastes, special attention will be paid to the development of magnetic nanoparticles with desired size, but also functionalized according to the polymeric component of the paste.
