Advanced Science, EarlyView.Fibrotic scarring persistently challenges urethral reconstruction. This study introduces a conformal, wearable ultrasound bioelectronic system that overcomes this by reprogramming fibroblast fate. The device activates a developmental Wnt–FGF10 axis, driving fibroblasts toward a regenerative FGF10+ phenotype that promotes angiogenesis and matrix ...

Vibration piezoelectric energy harvesting
, 2016 Energy harvesting is the conversion of ambient energy present in the environment into electrical energy, which is accumulated and stored for later use. It has the same principle as large-scale renewable energy generation (such as wind or solar power) but it is very different in scale.
