A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

AI‐Enhanced Vibrational Capsule for Minimally Invasive Detection of Abnormal Bowel Tissue

Advanced Science, EarlyView.
A fully integrated vibration‐assisted capsule is presented for the minimally invasive detection of bowel lesions. The capsule incorporates a wireless sensor and an eccentric motor to probe tissue mechanics in situ. By coupling triaxial vibration signals with AI‐based classification and analytical modeling, the system enables early, non‐visual ...

Brain‐Adhesive Bioelectronics With Shape‐Morphable and Biodegradable Properties for Stable Brain Signal Monitoring

Advanced Science, EarlyView.
A brain‐adhesive sensor (B‐Sensor) was developed by integrating a self‐healing biodegradable elastomer, a tissue‐adhesive hydrogel, and molybdenum electrodes. The B‐Sensor adheres to brain tissue, conforms to cortical curvatures, and maintains stable electrical performance over the intended period for reliable recording of spatiotemporal brain activity
