Level of Acceptability of Electricity Generating Insole

Abstract

The increasing emphasis on sustainable and renewable energy sources has grown in recent years. This focus has led to increased research and development efforts aimed at harnessing energy from unconventional and previously untapped sources. One such area of innovation is the concept of electricity-generating insoles, most of which utilize piezoelectric materials. This aims to convert mechanical energy generated while walking into usable electrical energy.

This study applied the quantitative-descriptive research method with purposive sampling. The survey questionnaire was utilized as a research instrument to measure the level of acceptability of the proposed model in terms of materials used, power generating capacity, charging capability, safety, and presentation. For the statistical analysis, specifically, the t-test was utilized to discern variances in the assessments of the two groups of respondents.

The study compared the overall weighted mean and variance of mechanical engineers and electrical engineers, revealing values of 3.28 with a variance of 0.07825 for mechanical engineers and 3.31 with a variance of 0.09675 for electrical engineers. With a t-computed value of 0.1604 and a t-critical value of 2.036 at a 0.05 percent significance level and 8 degrees of freedom within groups, the null hypothesis was accepted. Further analysis showed that mechanical engineers obtained higher composite means in various aspects, such as Materials Used (3.45 highly acceptable for mechanical engineers and 2.8 lowly acceptable for electrical engineers), Power Generating Capacity (2.35 lowly acceptable for mechanical engineers vs. 2 lowly acceptable for electrical engineers), Charging Capability (3.45 highly acceptable for mechanical engineers and 2.56 acceptable for electrical engineers), Safeness (3.6 acceptable for mechanical engineers and 2.88 acceptable for electrical engineers), and lastly, for Presentation (3.85 as highly acceptable for mechanical engineers while the Electrical Engineers got 3.08 as acceptable).

For further improvement of the study, the following recommendations were provided by the respondents: in terms of materials used, the respondents advised to further explore advanced energy storage solutions such as high-capacity batteries or super capacitors to store harvested energy efficiently and deliver it when needed, ensuring continuous and reliable power supply to the user.
