Temporary Tattoos May One Day Power Your Wearable Medical Devices

Summary

Penn State engineers developed paint-on temporary tattoos using conductive ink to power wearable medical devices. These tattoos can monitor brain, heart, and muscle activity, offering a more durable and customizable alternative to traditional electrodes, with potential applications in early disease detection and prosthetics.

Key Takeaways

1. Penn State University engineers aim to change this with paint-on tattoos that use conductive ink to power sensors for wearable devices such as EEGs, ECGs and EMGs that track brain, heart and muscle activity, respectively.
2. The hope is that these temporary electrode tattoos can help spot heart attacks early, read brain waves or power robotic prosthetics.
3. When experimenting with the ink, the Penn State team found that the painted electrodes could monitor ECG signals for up to 12 hours.
