Abstract

Chronic wound healing remains a clinical challenge due to the limited capacity of conventional therapies to accelerate tissue regeneration. Electrical stimulation (ES) offers a promising therapeutic modality; however, open-loop ES cannot adaptively adjust therapy duration. This study developed a closed-loop ES system incorporating fuzzy controller to dynamically regulate stimulation duration based on wound progression. The method integrates an Atmega32-based ES platform, fuzzy controller algorithms, and preclinical testing on guinea pigs. The ES system operates at a frequency of 20 Hz, a pulse width of 250 µs, and an output voltage of 50 V. The fuzzy controller adjusts stimulation duration within a range of 15–45 minutes according to the difference between the actual and target wound areas, achieving an estimation error of 0.3%. Preclinical evaluations compared the therapeutic effectiveness of closed-loop ES, open-loop ES, and no-ES conditions. Wound-area reduction over seven days in the closed-loop group reached 64–67%, higher than the open-loop (44–50%) and no-therapy (47%) groups. Closed-loop therapy also produced the highest tissue-density outcomes (75–100%), exceeding those of the open-loop (50%) and no-therapy (25–50%) groups. The fuzzy-controlled closed-loop ES accelerated tissue regeneration by approximately 1.5–2 times compared to open-loop and no-therapy conditions. Effectiveness rankings showed the closed-loop system achieving the highest scores (0.90 and 1.00), outperforming the open-loop (0.61) and no-therapy (0.51) groups. These findings indicate that fuzzy-controlled closed-loop ES provides superior wound-healing performance compared to conventional approaches, offering a more adaptive and precise therapeutic strategy with potential for broader medical application.

Abstract

In the fashion lifestyle industry, emotional connections with consumers have become increasingly important in fostering brand loyalty. This study aims to examine the influence of brand attachment and brand love on brand loyalty among Havaianas consumers. A quantitative survey was conducted involving 108 respondents selected through purposive sampling. Data were analyzed using multiple linear regression with SPSS. The results indicate that both brand attachment and brand love have positive and significant effects on brand loyalty, with brand love showing a stronger influence. The findings imply that companies should strengthen consumers’ emotional experiences to enhance long-term brand loyalty.
