New paint-on health sensors are as fun as face paint

Penn State engineers have developed colorful conductive ink that can be painted directly onto skin to monitor electrical signals from the heart, brain, and muscles. The customizable electrodes remain accurate during movement, can control a robotic prosthetic, and may eventually measure biomarkers such as glucose and cortisol.

宾夕法尼亚州立大学的工程师研发出一种可直接涂在皮肤上的彩色导电墨水，用于监测心脏、大脑和肌肉产生的电信号。这种可定制的电极在人体活动时仍能准确工作，还可用于控制机器人假肢，未来或许能够测量葡萄糖和皮质醇等生物标志物。
