Advancements in flexible neuromorphic and sensor technology
Overview
Recent scientific developments have focused on advancements in flexible, neuromorphic, and sensor technologies.
Initial reports highlighted the creation of the mAxialtrode, a needle-thin, polymer-based brain implant capable of recording electrical activity, delivering drugs, and providing optical stimulation. Alongside this, researchers developed a humidity-sensitive memristor made from porous nickel pyrophosphate that can detect moisture with over 97% accuracy and ‘remember’ levels by altering electrical resistance.
Subsequent research from Dongguk University introduced a self-powered, flexible neuromorphic device designed to mimic biological tactile sensing. By integrating a graphene-channel ion-gel-gated transistor with triboelectric nanogenerators, the device converts mechanical energy from touch or movement into electrical pulses, eliminating the need for external batteries. This system demonstrates various memory durations and spike-rate-dependent plasticity, allowing it to be used for human-activity recognition in neural networks.
