Non‐Invasively Tracking an Arbitrary Deformable Object Through Scattering Media and Around Corners via Speckle Correlations

Advanced Science, EarlyView.
A speckle correlation centroid localization method (SCCLM) is proposed for non‐invasive tracking of an arbitrary deformable object through scattering media and around corners, requiring no prior information. Its effectiveness is demonstrated not only in tracking hidden objects beyond the memory effect region but also in following objects undergoing ...

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

Advanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Shadow‐Calibrated Stereo Vision for Colorimetric Sweat Analysis

Advanced Science, EarlyView.
By establishing a mathematical model that reconstructs 3D structures through geometric features of object shadows under controlled illumination, and combining it with Convolutional Neural Network‐based 2D image analysis for volumetric calibration, this work enables highly accurate 3D morphological reconstruction.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

Advanced Science, EarlyView.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.
