 Effective communications are central to all military operations. The Chemical Communications program is exploring innovative methods to develop self-powered chemical systems that can encode an input string of alphanumeric characters (i.e., a message), convert the message to a modulated optical signal, and transmit it repetitively to a receiver.
The ultimate goal of this program is to develop a small replicator device, with the form factor of a Personal Digital Assistant (PDA) or cell phone that―
- Permits the user to input an arbitrary 60-character alphanumeric message.
- Translates the message into an appropriate set of modulated chemistries.
- Embeds these chemistries into a disposable substrate (the transmitter).
- Ejects the substrate for deployment.
The replicator device will enable warfighters to generate disposable optical transmitters in real time, each with a user-specified message. It will be compact, lightweight, and powered by batteries or solar cells.
