Iontronic devices

Iontronics started as a concept of controlling electronic devices using ions. Now in iontronics, ions are used to transmit, generate and store signals. This is interesting for neuromorphic applications, new computing methods, and reduction of the energy consumption in information processing.

In our lab, a new iontronic device called ion voltage effect soft triode (IVEST) was built. The IVEST has controllable linear ohmic output and showed amplification behavior and memory effect reaches up to 6 hours. We are currently making investigations to improve the understanding of the mechanism of the device, to optimize the parameters, and to integrate them it in electronic circuits. We see them as building blocks for new computational systems.
