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...
