Goldsmith and Farsad's research aims to create a system that uses chemicals to transmit messages. Instead of zeros and ones, their system uses an acid-base combination. The complications of this type of system are largely due to the fact that it's completely new. Goldsmith has spent her entire career working in wireless communication. Chemical messaging offers a new twist on familiar problems.
One potential of chemical-based data exchange is that it could be self-powered, traveling throughout the body harmlessly – and undetectable by outside devices. "This is one of the most important potential applications for this type of project," Farsad said. "It could enable the emergence of these tiny devices that are working together, talking together and doing useful things."
While working to improve their current chemical texting system, Goldsmith and Farsad are also collaborating with two bioengineering groups at Stanford to make human body-friendly chemical messaging a reality.
