Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Integrated Flexible Zwitterionic Electrochemical Sensor Platform for Real‐Time Salivary Glucose Quantification

Advanced Sensor Research, EarlyView.
A flexible electrochemical sensor platform can enable continuous, real‐time monitoring of salivary glucose for applications confined to spaces such as the oral cavity. Surface modifications with Prussian blue, chitosan, and zwitterionic polymers enhance sensitivity, selectivity, and antiadherent performance.
