Study on Vibration-Based Energy Harvesting from Industrial Machinery Vibration for Low-Power Sensor Devices Use
(GMIT, 2025) Tulga Avarga; 1 st Supervisor: Prof. Ph.D. Odbileg.N; 2 nd Supervisor: Prof. M.Sc Myagmarjav.B
The growing demand for sustainable and maintenance-free power sources in
industrial environments has driven the exploration of ambient energy harvesting
technologies. This thesis investigates the use of vibration-based energy harvesting from
industrial machinery as a power source for low-power sensor devices. By focusing on
piezoelectric transduction, the study presents the design, modeling, and testing of a
small-scale energy harvester prototype built around Arduino, piezoelectric elements, and
passive power electronics.
Field measurements were conducted on vibrating machinery such as motors and pumps
operating at 30 Hz and 50 Hz to characterize real-world excitation sources. A cantilever
piezoelectric beam made of PZT-5A was designed and analyzed using ANSYS
Workbench to determine its natural frequency and harmonic response. The harvester's
electrical behavior was simulated using MATLAB/Simulink, and the system's real-time
performance was evaluated using a function generator, oscilloscope, and the MPU6050
accelerometer module.
The results showed that the harvested voltage ranged from a few hundred millivolts up
to ~1.0 V, depending on vibration intensity. The time-domain and frequency-domain
Analysis revealed a clear correlation between vibration frequency and harvested voltage.
The system reliably activated an LED when the voltage exceeded threshold levels,
confirming functionality. Simulation results closely matched experimental data,
supporting the validity of the proposed model.
This work concludes that piezoelectric vibration energy harvesting is a viable power source
solution for autonomous industrial sensor applications. While not yet suitable for
With continuous power delivery, the proposed system can effectively support intermittent
sensing tasks, reducing battery dependence, and enabling the sustainable deployment of
low-power monitoring devices.
Smart Cottage Automation: Electrical Installation and calculation, Designing, Possibility of Renewable energy integration:
(GMIT, 2025) TAMIRTULGA Ganbold; 1 st Supervisor: Mr. Nikita Abramov; 2 nd Supervisor: Mr. Bold Enkhbold
This thesis presents the design and feasibility analysis of a smart, energy-efficient
cottage tailored for Mongolia’s harsh climate and evolving lifestyle needs. In response to
increasing urban overcrowding, air pollution, and a growing interest in countryside living,
The project proposes a technologically integrated and sustainable residential model for
families of four to six members.
The study covers every core aspect of the cottage from architectural and electrical
planning to material selection, energy consumption modeling, and the integration of
home automation and renewable energy systems. The design prioritizes energy
conservation by using high-performance, locally available materials such as MAK
Euroblock, triple-glazed Windoor systems, and Mongol Basalt insulation. Electrical loads
were calculated across seasonal variations, with detailed planning for wiring, circuit
protection, and special loads like oil-based electric heating.
To enhance comfort, security, and efficiency, the cottage incorporates a Tuya-based
An IoT home automation system, enabling remote control of lighting, heating, and
surveillance. A hybrid off-grid energy system, combining solar photovoltaic panels and
wind turbines, was sized using real-world climate data from the Global Solar and Wind
Atlas. Energy demand modeling, along with storage and inverter sizing, confirms that the
system can provide continuous power throughout the year, even in the demanding winter
months.
While the project demonstrates strong potential for energy independence and smart
living, certain aspects remain undeveloped, including plumbing design, detailed
interior/exterior architecture, roof structure finalization, and overall construction cost
estimation. Nevertheless, the smart cottage stands as a promising and scalable solution
that balances modern convenience with environmental sustainability, offering a vision for
a more autonomous, efficient, and connected lifestyle in rural Mongolia.
