Remote Detection of Electronic Devices

Non-Linear Junction Detection is a well-known technique for detecting electronics that utilize semiconductor (solid-state) junctions. The current state of the art for finding hidden electronics — such as electronic eavesdropping devices — using this technology has a maximum range of about 2 m, and more...

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...
