Design and characterization of screen-printed piezoresistive cantilever for gas sensor application

2022-01-01 , Naouras Saleh , Nursabirah Jamel , Nawi I.M.

In this paper, the design, and the characterization of screen-printed cantilever-based humidity sensor are described. The project investigated in detail the sensitivity, and fabrication process of screen-printing based sensor with coated active humidity material on cantilever's free end. The main aim of this paper is to compare the screen-printed technology with other existing technologies like micro-electro-mechanical system (MEMS), and low temperature cofired circuit (LTCC). The sensor has been simulated under different level of relative humidity with two different temperature value: 35°C, and 45°C. This paper also represents an analytical and mathematical modeling approach for frequency shift and thick film resistance change of the selected sensor. The analytical results are compared with the simulated results.

Harvesting energy by capturing vibration from low frequency energy have been explored extensively. In essence, a single piezoelectric transducer or an array of piezoelectric connections are used to convert kinetic energy into electrical energy in order to produce low frequency energy. In this paper, multi-configuration array piezoelectric connections are used to investigate the performances of different converter circuit types in low energy harvesting applications. This research utilized three pieces of circular piezoelectric sensor to test the combinations of array connection. There are four options for the piezoelectric sensor configuration: parallel (P), series (S), parallel-series (PS), and series-parallel (SP) while the full wave bridge rectifier (FWBR), parallel voltage multiplier (PVM), and parallel Synchronized Switch Harvesting on Inductor (P-SSHI) converter circuit are chosen AC-DC converter circuits. The system is assessed using a variety of load configurations, including 10 kω and 1 Mω with a 3 Hz input frequency. In order to produce the highest possible output of collected power, the observation focuses on identifying the ideal combination of array piezoelectric connections with AC-DC converter. The result shows that 3-Parallel (3P) piezoelectric connection obtained a higher power output among the other types of array piezoelectric which was 5.97μW. The FWBR circuit generated the highest output power with 2.42μW for a combination of piezoelectric sensors array of 3P connection with the AC-DC converter.

Effect of different types of blades on miniature wind turbine energy harvesting output

2020-01-07 , Umar M. , Nursabirah Jamel , Norkharziana Mohd Nayan

This paper presents a simulation and experimental setup for miniature wind turbine energy harvesting using different types of material and blades. Three different cut in wind as low as 3.34 m/s, 4.00 m/s and 5.12 m/s were used to evaluate the miniature wind turbine. MATLAB software is used to design and run the simulation of the system. The result shows that type A PVC blades with the radius of 0.035 m provides the highest output with 19.41 V during cut in wind of 5.12 m/s.
