A Solar Powered Wireless Computer Mouse: Design, Assembly and Preliminary Testing of 15 Prototypes

Abstract

The concept and design of a solar powered wireless computer mouse has been completed, and 15 prototypes have been successfully assembled. After necessary cutting, the crystalline silicon cells show satisfactory efficiency: up to 14% when implemented into the mouse device. The implemented voltage conversion unit that is needed to increase the solar cell voltage for charging one single or two series connected NiMH batteries, has a conversion efficiency of up to 50%, which leaves room for further improvement. In the coming months, an extensive user test will be conducted, including user-related aspects such as the willingness to pro-actively sun-bath the mouse.
