      Systems that monitor environments often rely on cumbersome wires to supply power to the sensing equipment or batteries that require monitoring and replacement. As technologies continue to advance, the use of self-sustaining, wireless powering becomes more essential to satisfy challenging requirements that necessitate continuous measurement and general functionality. This paper focuses on the creation of a wireless sensor network with emphasis on the implementation of wirelessly charged sensing nodes by utilizing microwaves. Three subsystems make up this "proof of concept" wireless sensor system: a power transmitting base station, three sensor nodes, and a communication base station. Interfacing and power regulation are of the utmost importance in order to ensure all of the subsystems are able to communicate with one another and power all necessary functions. The power transmitting base station transmits microwaves to the nodes. A rectenna on each node converts the transmitted microwaves into DC power. Each node contains sensors to monitor the temperature and light of the environment. For the communication aspect of the system, Zigbee protocol, which belongs to IEEE 802.15.4 protocol, is used fore wireless communication between the base station and the nodes. Through the combination of power regulation, microwave energy, and radio transmission, users are able to utilize this system to collect environmental sensor data wirelessly.

      This paper describes the design and implementation of electroluminescent light suits used by the BYU Ballroom Dance Team. The suits are controlled via a radio. The light suit design process comprised suit design and construction, control box design and construction, and a GUI implementation for a transmitting laptop station. These tasks were divided between nine team members and completed over a three-month time period. Each task had its own challenges, but through the hard work and dedication of team members, the project was successful.
