Over the years, society has evolved technologically to the point where we become dependent on technology. Today, nearly everybody have smartphone devices. This leads to the popularity of portable chargers since portable devices do not have a constant source of power. Even most portable chargers share the same problem as portable devices, which they both share a finite amount of battery power before needing to recharge at a power outlet. Ultimately, they are just temporary solutions to the problem of the lack of power. However, society assumes the abundance of electric power sources where they view them as an infinite …

Currently, most cell phones utilize wired adapters to charge, which cause a minor hassle when one frequently needs to unplug and replug their device whenever they pick it up to use while it is charging. The charging adapter is a pad that phones can be placed on to wirelessly charge the device. The charging adapter consists of two components: the wireless charging platform to supply and transmit the power, and the wireless charging receiver for phones that do not already have an internal receiver included, specifically targeting newer generation iPhones that utilize a lightning port (i.e. iPhone 5, 6, 6s, …

This project focuses on creating a device to differentiate between various types of metals via magnetic induction. Magnetic induction is used because it is both non-optical and non-contact. It achieves this by generating a varying magnetic field, which induces eddy currents in the metal. These eddy currents produce small disturbances in the surrounding magnetic field, which can be sensed with Hall Effect Sensors (HES). The primary challenge in this project was generating a sufficiently strong magnetic field to detectable disturbances. In order to achieve better results, a stronger magnetic field must be used as well as more sensitive Hall Effect …

Phones are now an integral component in the daily lives of people. Smartphones give access to movies, internet, and even books. This versatility and increased use can also lead to a shorter battery life. A phone with video viewing capabilities will be a heavy load on the unit’s battery. With phones utilizing 3G and 4G technology, even heavier demands are placed on the battery. As technology improves even further to provide for a larger entertainment experience on the phone, this could also lead to further battery degradation if the current battery situation isn’t addressed. To have a fully operational phone …
