SU Global Exponential Medicine – self-healable electronic skin

Daniel Kraft, Faculty Chair for Medicine and Neuroscience for Singularity University and Founder and Chair of Exponential Medicine, gave a very information dense talk on Exponential medicine. There were perhaps a hundred slides in 20 minutes.

Daniel gave a 48-minute talk with similar information in Japan 11 months ago in Japan. The new talk had a lot of updated material.

In today’s talk, Daniel discussed the shift in medical devices.

The first stage is Buildable => Moveable => Carriable => Wearable.

Then beyond that are Insideables. There are many devices that can go inside the body.

Ingestibles – electronics that are inside pills
Trainables = This is where a smartphone app exchanges information with wearables sensors to detect posture. The app then helps guide people to have correct posture. Certain extreme slouching can cause severe strain and serious conditions.

There are a variety of wearables.
Sleepables = Apps and devices to help improve the quality of sleep
Breathables = analyzing the breath to diagnose disease
Sweatables = smart patches to analyze the sweat for diagnosis
Shake’ables = monitor Parkinson tremor progression

There will be several Nextbigfuture articles that take a deeper dive into the large amount of information in this talk.

This first article will focus on new research in Nature Nanotechnology.

An integrated self-healable electronic skin system fabricated via dynamic reconstruction of a nanostructured conducting network.

Electronic skin devices capable of monitoring physiological signals and displaying feedback information through closed-loop communication between the user and electronics are being considered for next-generation wearables and the ‘Internet of Things’. Such devices need to be ultrathin to achieve seamless and conformal contact with the human body, to accommodate strains from repeated movement and to be comfortable to wear. Recently, self-healing chemistry has driven important advances in deformable and reconfigurable electronics, particularly with self-healable electrodes as the key enabler. Unlike polymer substrates with self-healable dynamic nature, the disrupted conducting network is unable to recover its stretchability after damage. Here, we report the observation of self-reconstruction of conducting nanostructures when in contact with a dynamically crosslinked polymer network. This, combined with the self-bonding property of self-healing polymer, allowed subsequent heterogeneous multi-component device integration of interconnects, sensors and light-emitting devices into a single multi-functional system. This first autonomous self-healable and stretchable multi-component electronic skin paves the way for future robust electronics.
