summary
● Electric communication utilizing conductivity of seawater
● Transmitter : metal electrode
⇔ Receiver : transistor shape sensor operating in solutions
● Apply square wave voltage to metal electrode
➡ Pulse wave is transmitted to the receiver
● Transmitter : metal electrode
⇔ Receiver : transistor shape sensor operating in solutions
● Apply square wave voltage to metal electrode
➡ Pulse wave is transmitted to the receiver
predominance
● Using ionic conduction ➡ high speed and isotropic propagation
● Compact and low power for both transmitter and receiver
● Using diamond for transistor ➡ stable operation in seawater
