Demo: A Non-invasive and High-speed Molecular Communication Testbed with Capacitive Sensing

Many molecular communication (MC) prototypes documented in the existing literature necessitate intrusion into the communication channel during the signal detection process, potentially posing harm to the organism. Addressing this concern, we present a non-invasive MC testbed in this demonstration employing the capacitive sensing mechanism to capture chemical signals. The chemical substances utilized in our testbed are soybean oil and water, exhibiting distinct permittivity characteristics. To the best of our knowledge, our testbed has achieved the highest attainable data rate, reaching up to 7.14 bit/s, surpassing other non-invasive MC platforms.
