Prof. Young-Ho Cho’s group has developed a skin-attachable pulsewave sensor with haircell structures capable of wicking sweat rapidly from the skin with increased pulsewave detection accuracy. The breathable sensor reduces the skin redness and itching caused by conventional wearable biosensors that trap sweat beneath them, while the haircell structures achieve conformal contact to the skin with a larger contact area for higher pulsewave detection accuracy....read more
