Triboiontronics based on dynamic electric double layer regulation

The regulation and application of ion carriers in the electric double layer is challenging. In this issue of Matter, Wei et al. propose a concept of "triboiontronics" based on triboelectrification regulation, breaking through the barrier of ion arrangement regulation through electronics with higher energy transfer efficiency.

Triboiontronics for efficient energy and information flowLi et al.MatterSeptember 20, 2023In BriefThe electrical double layer (EDL) structure has been investigated for over a century, but how to fine-tune it remains a challenge. Here, dynamic regulations of EDL were achieved by contact electrification, forming triboiontronics. Through regulating the diffuse layer and Stern layer, an efficient direct-current triboiontronic nanogenerator and a bionic neurologic circuit were constructed. It provids an interdisciplinary paradigm of charge regulation for prospective applications and offers a platform to study the ionic-electronic coupling interface for efficient energy and information flow.
