Gelatin–Organic Acid‐Based Biodegradable Batteries for Stretchable Electronics

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
In this study, two organic acids are incorporated into gelatin electrolytes for magnesium–molybdenum batteries. In the results, it is demonstrated that both organic acids increase gelatin conductivity and improve electrochemical reactions in battery, leading to higher plateau voltage and greater battery capacity.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

Kinematic rate control of simulated robot hand at or near wrist singularity [PDF]

open access: yes
A robot hand should obey movement commands from an operator on a computer program as closely as possible. However, when two of the three rotational axes of the robot wrist are colinear, the wrist loses a degree of freedom, and the usual resolved rate ...
