Application of shrink induced three-dimensional structures to biosensor systems integrated with flexible solar cells

It is desirable to develop self-powered biosensor systems with better performance and lower cost by integrating a solar cell. A simple, controllable, and low-cost approach is showed to create three-dimensional microstructures in both biosensors and solar cells. This three-dimensional microstructure can enhance the performance of both biosensors and solar cells. The entire system was connected to a computer through a USB control unit. This self-powered biosensor system integrated with communication technology will have a great impact on point-to-care medical applications. It is anticipated that the controllable shrink induced micro structures will represent a general low-cost approach to accelerate the development of biosensors and photovoltaic devices.
