Multiphysics simulations and electromechanical testing of macro- and micro-scale actuators, sensors and energy harvesters based on smart materials
Summary:
A University institute in Lithuania specialises in simulation-assisted design, rapid prototyping and electromechanical testing of macro/micro/biomechatronic systems. Key competences include multiphysics modeling and dynamic characterisation of MEMS transducers with focus on piezoelectric sensors, actuators and vibration energy harvesters. The institute seeks commercial or research cooperation agreements with industry or public bodies in the field of smart miniaturised systems.
Description:
An institute is a division of a Lithuanian university, which is one of the leading technological universities in the Baltic states. The institute is a national single-sited mechatronics research infrastructure, which operates on open access basis. It provides facilities and R-Y-D services in the field of multiphysics modeling, mechanical/electrical/optical characterization, machining and rapid prototyping of a broad scope of mechatronic devices including sensors, actuators and small-scale kinetic energy harvesters based on smart materials. Due to its multidisciplinary nature the institute serves the needs of researchers working in such engineering fields as mechanics, electronics and IT as well as supports companies from different manufacturing industries in development of high value-added products.

The institute offers the following specific expertise:
1) Numerical modeling of different transducers used in micro-electro-mechanical systems (MEMS) with focus on multiphysics finite element simulations aimed at proposing rational designs with tailored performance. Typical examples include:
- Piezoelectric vibration energy harvesters including wideband configurations targeted for low-frequency applications (e.g. wearable devices or wireless sensors for structural or machine monitoring). Implemented design approaches include exploitation of contact or noncontact (magnetic) interactions for efficient micropower generation using frequency up-conversion.
- Piezoelectric nanostructures for pressure sensing or mechanical energy harvesting. Competences include dynamic simulations of electromechanical response of ZnO nanowires including polymer-encapsulated arrays, piezoelectric-semiconductor coupling, Schottky contacts, external circuit, etc.
- Electrostatic MEMS actuators (e.g. microswitches). Competences include numerical study and optimization of dynamic behavior including pull-in, impact interaction and different coupled-field phenomena (e.g. squeeze film damping, residual stresses, etc.).
2) Fabrication of mechanical prototypes using subtractive (e.g. CNC machining) and additive technologies (polymer 3D printing: nylon 12, ABS, photopolymer).
3) Optical, mechanical and electrical characterization of macro- and micro-scale structures:
- In-depth dynamic characterization (modal analysis) of: i) macro structures using Polytec 3D laser Doppler vibrometer, rotational vibrometer, holographic interferometry (vibration testing using electrodynamic shaker up to 6.3 kHz and 100g with loads up to 25 kg); ii) micro structures using Polytec scanning-type laser Doppler vibrometer and stroboscopic video microscopy, which enable out-of-plane/in-plane measurements of structural vibrations in probe stations both in ambient conditions and in high-vacuum at elevated temperatures (up to 200 deg.C).
- Electrical characterization of MEMS components using probe measurements under controlled vacuum/temperature conditions.
- Surface topography characterization using scanning white light interferometry.
- Nanoindentation and scratch measurements for extraction of elastic modulus, hardness parameters, adhesion failure of thin films, etc.
- Static, dynamic (fatigue-related), impact mechanical testing.
- Rheometry (e.g. MR fluids), magnetic field measurements, high-speed infrared imaging, digital capture of ultra-fast processes, high-resolution 3D laser scanning of small-/large-volume components in full color.
The institute seeks to collaborate on a basis of commercial contract or publicly funded project with any academic, research or industrial partner that is interested in the expertise offered. In particular, the institute seeks to become a research partner in H2020 projects (e.g. in LEIT "ICT" and "NMPB" Work Programmes).
Advantages and Innovations:
The institute offers advanced multiphysics simulation and vibration testing expertise in the field of piezoelectric devices with recent efforts mainly associated with:
- Research and development of wideband piezoelectric vibration energy harvesters (micropower generators) for industrial and wearable applications (e.g. smart devices).
- Multiphysics modeling of piezoelectric nanostructures (e.g. ZnO nanowires) taking into account effects of semiconductor physics, polymer encapsulation, nonlinear contact interactions, external electrical circuit, etc.
The institute possesses the widest range of Polytec state-of-the-art laser Doppler vibrometers in the Baltic region including 3D, scanning and rotational vibrometers. They enable full dynamic characterization of both macro- and micro-scale structures including probe testing of microsystems components under controlled vacuum conditions at elevated temperatures.
