Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 1. By: M.Jayalesh B.Gurumoorthy II-ECE A PIEZOELECTICITY AND ITS APPLICATIONS
- 3. INTRODUCTION 1. Piezoelectricity was discovered by Curie brothers in 1880. [Paul – Jacques Curie] 2. It is the generation of eletric field form applied proesson. 3. It is observation in cryslline materials with no inversion symmetry. 4. The materials exhibiting the direct piezoelectric also exhibit the revese piezoelectric effect(the internal generation of a mechanical strain resuling from an applied electrical field).
- 5. PIEZO TRANSDUCER Pressure Port Force Summing Member Crystal Output Voltage Base
- 6. Gas lighter
- 8. PRIME APPLICATION PIEZOELECTRIC ENERGY HARVESTING
- 10. GYMS AND WORKPLACES Vibrations caused from manchines in the Gym
- 11. MOBILE KEYPADS & KEYBOARDS Crystals laid down under keys of mobile unit and keyboard. For every key pressed vibration are created. These vibrated can be used for charging purposes.
- 12. POWER GENERATING BOOTS OR SHOES Idea was resaeched in US. To power the battlefield equipment by generators embedded in soldier boots. Idea was abandoned due to the discomfort.
- 13. FLOOR MATS AND PEOPLE POWERED DANCE CLUBS Series of crystals cna be laid below the floor mats, tiles and carpets. One footstep can only provide enough electrical current to light two 60-wattbullbs fot one second. [source:Christian Science Monitor].
- 14. When mob uses the dance floor , an enormousvoltage is generated. This energy is uesd to power the equipment of nightclubs.
- 15. OUTPUT POWER The output voltage obtained from a single piezoelectric crystal is in millivolt(mV) range, which is different for different crystals. And the wattage is in microwatt range. In order to achieve higier voltages, the piezoelectric crystals can be arranged in series. Used to change batteries for backup supplies or to power low-power microprocessors.
- 16. OTHER APPLICATIONS: Electric cigarette lighter: Pressing the button of the lighter causes a spring-loaded hammer to hit a piezoelecric crystal, producing a sufficiently high voltage that electric current flows across a small spark gap, thus heating and igniting the gas. As sensing elements: Detection of pressure variations in the from of sound is the most commom sesor application, e.g. Piezoelectic materal, creating a changing voltage.
- 17. ADVANTAGES: Unaffected by external eletromagnetic fields. Pollution Free Low Maintenance Easy replacement of equipment.
- 18. DISADVANTAGES: Crystal is prone to crack if overstessed. May get affected by long use at high temperatures.
- 19. CONCLUSION Piezoelectrcity is a revolutionary source for “GREEN ENERGY”. Convert the ambient vibration energy surrounding them into electrical energy. Electrical energy can then be used to power other deviecs or stored for later use.
- 20. THANK YOU
