“…We decided early on that our product would revolve around turning mechanical energy into electrical energy. Since we wanted to keep our product small, compact, and easy to use we looked into different products that convert mechanical energy into electrical energy while being small and user friendly [4]- [9]. The idea of using a dynamo, which created electricity by moving a magnet in a coil of wires, seemed like a good idea to us.…”

It is more challenging to maneuver and perform your daily chores and activities during the wintertime. Working in a cold environment can cause several adverse effects on human performance and health. Workers suffering from exposure to the cold can experience thermal discomfort, increased strain, decreased performance, and cold-related diseases and injuries such as frostbite and hypothermia. The winter season makes it challenging to go outside and perform outdoor chores and activities without the proper attire. Keeping your hands warm is especially crucial because they lose heat very fast if exposed directly to the elements. There is only so much warmth that a thin layer of fabric can provide. On those extra chilly days, the freezing temperatures and blistering winds can seemingly cut right through your gloves and leave your fingers numb. In this paper, we develop a self-heated glove with power generated from the movement of your hand. Like a squeeze flashlight, the depression of a handle will power a motor and create an electrical current. As the current flows through the heating plates woven into the glove's fabric, the plate will release heat to the glove. By using the power of your hands, you will stay comfortable and warm while enjoying outdoor winter activities. The paper also describes the prototype, data, and future applications of the system. What's more, this work teaches students to master various skills, such as research, collaboration, design, construction, and technical writing.

Piezoelectricity is the charge accumulated in certain solid materials due to applied stress (mechanical stress or vibration, such as sound waves). This unique characteristic makes these materials very suitable for use as sensors to convert mechanical vibrations into signals, such as for guitar pickups and record players. The reverse is also true. By applying a voltage to the piezoelectric material, it vibrates and produces sound, which can be used as a buzzer and a small speaker. As demand for renewable energy increases, the use of piezoelectricity as a source of energy harvesting has become of interest.In recent years, it has been recognized that piezoelectric devices can be used for many purposes for low-energy mechanical sources (such as pedestrian traffic) and larger-scale passive power generation in the California highway system. Many of these methods of large-scale piezoelectric energy harvesting come with the challenge of finding an efficient way to integrate the piezoelectric transducer into existing infrastructure. By using different methods, piezoelectric sensors can be placed on wheels to generate energy on a smaller scale. This study explores this method by designing a prototype wheel to evaluate the effectiveness of arranging piezoelectric sensors radially along the outside of the wheel to generate passive electric energy from the contact of the wheel with the ground. We hope that this idea could either work in the real world or lay the groundwork for the next generation. In addition, these project-based experiential learning activities help students to master various skills, such as research, collaboration, design, construction, and technical writing, and more. The skills learned by this project were invaluable and important experiences within engineering. This Energy Wheel not only provides scientists and engineers with more valuable information about alternative energy, but also is capable of educating the everyday person about the basics of engineering as well as the importance of renewable resources.

As humanity faces the consequences of climate change due to the widespread use of fossil fuels, the need for renewable energy is as urgent as ever. With 17.5% of global emissions coming from electricity production, we must reduce emissions before the planet becomes uninhabitable. We do this by creating more forms of renewable energy [1]- [4]. As the impact of fossil fuels becomes more apparent, we as a society urgently need to produce and use renewable energy. Unprecedented amounts of energy are already being generated every day that are not being used. Therefore, we decided to target one place that generates a lot of power per hour: the gym.Systems such as dynamo generators are standard in many handheld devices. The aim is to develop a miniature generator that connects to various machines commonly found in gyms and uses rotational energy to generate electricity. This energy will be collected by a universal box that can be attached to machines with rotational motion, such as cable machines or stationary bicycles. Connected through a personalized attachment, the machines would turn motors to generate energy. We can use this harvested energy to help power the gym itself, which can significantly reduce utility costs.
