Bio-Inspired Hydrogel Electrode for Plant-Leaf Signals: IJASC

Sat, 28 Feb 2026 00:00:00 +0000

A co-first-authored paper introduces a hydrogel-integrated, octopus-inspired adhesive (H-OIA) patch with an engineered silicone interface that conforms to the rough, variably-hydrated surface of plant leaves. On Coffea arabica, it enables stable long-term recording of stimulus-responsive plant bioelectrical signals where conventional electrodes detach.

Octopus-Inspired Adhesive Electrode for EMG: IJIBC

Sat, 28 Feb 2026 00:00:00 +0000

A co-first-authored paper presents an octopus-inspired adhesive electrode whose microstructured suction architecture keeps conformal skin contact and stable EMG signals under both dry and wet conditions. It addresses the detachment and signal degradation that limit EMG-based control of prosthetics and wearable robots.

Octopus-Mimicking Soft Grippers: Review in Biomimetics

Thu, 04 Dec 2025 00:00:00 +0000

A co-first-authored review in Biomimetics surveys octopus-inspired soft grippers across three functional dimensions: structural and sensing devices, control strategies, and AI-driven applications. It maps suction-cup geometries, tentacle-like actuators, and hybrid designs toward more capable, intelligent soft robots.
