Performance Analysis of a Three-DOF Piezoelectric Vibration Energy Harvester
Abstract: Mechanical vibration energy can be transformed into electrical energy by a vibration energy harvester, which can then be stored in the battery for later use. It can convert vibrational motions like walking, leaping, running, etc. into pure renewable energy. This can turn previously squandered energy into energy that can be used to recharge wireless sensors and portable electronics. If these gadgets are used widely, they can produce a lot of …

Enhancing Worker Comfort in High-Heat Environments: A Triangular Bladeless Cooling Fan Approach
Abstract: Workers in high-heat industrial environments frequently encounter thermal stress, fatigue, and dehydration, which significantly impact both productivity and safety. Existing cooling solutions such as pedestal fans, ceiling fans, and central air-cooling systems often fall short due to limited airflow reach, safety concerns from exposed blades, high energy consumption, and poor suitability for dynamic workshop layouts. To address these challenges, this study presents a novel triangular bladeless fan designed specifically for …
