Flexible Silicon-on-Polymer Chip

A new, flexible, silicon-on-polymer chip was developed to augment new networked realities such as the Internet of Things. Typical silicon-based integrated circuits are brittle, rigid components packaged in a way that protects them. When these devices are put into a flexible form factor, rigidity is a negative...

Aerosol-to-Liquid Particle Extraction System (ALPES)

Agents that could be used in chemical and biological warfare tend to disperse widely in the air when released. Quickly collecting a concentrated sample of these agents is critical to detecting them before they reach harmful dose levels in the air. Also, methods of detection such as by...
