3D Printed Low‐Tortuosity and Ultra‐Thick Hierarchical Porous Electrodes for High‐Performance Wearable Quasi‐Solid‐State Zn‐VOH Batteries

open access: yesAdvanced Science, EarlyView.
This work presents an advanced 3D‐printed aqueous Zn‐VOH batteries system, and the important role of 3D‐printed low‐tortuosity structures in improving thick electrodes’ electrochemical kinetics (mass transfer and charge transfer) is highlighted. The promising potential of 3D‐printed quasi‐solid‐state Zn‐VOH battery devices in many practical wearable ...

Speech-dependent Data Augmentation for Own Voice Reconstruction with Hearable Microphones in Noisy Environments [PDF]

open access: yesarXiv
Own voice pickup for hearables in noisy environments benefits from using both an outer and an in-ear microphone outside and inside the occluded ear. Due to environmental noise recorded at both microphones, and amplification of the own voice at low frequencies and band-limitation at the in-ear microphone, an own voice reconstruction system is needed to ...

Real‐Time Wireless Detection of Heavy Metal Ions Using a Self‐Powered Triboelectric Nanosensor Integrated with an Autonomous Thermoelectric Generator‐Powered Robotic System

open access: yesAdvanced Science, EarlyView.
This study introduces a self‐powered environmental monitoring system that integrates a triboelectric nanosensor (TENS) with a robotic hand, controlled remotely by an exo‐hand and powered by a thermoelectric generator (TEG). The fully autonomous system detects Pb2⁺, Cr⁶⁺, and As3⁺ ions in real‐time and operates without external power, ideal for remote ...
