See What Scientists Just Created, Electronic Skin Nanomesh

   
   
Scientists have created a wearable device called "Gold nanomesh conductor" that can record data through skin. This wearable electronic skin nanomesh looks like a stylish gold tattoo, and it is ideal for long-term medical monitoring. The wearable tattoo is a step closer to eliminating larger health sensors, and it is so comfortable that people forget that they are wearing it.

We’re a little closer to getting rid of bulky health sensors now that scientists have created a super-thin wearable that can record data through skin. That would make this wearable, which looks like a stylish gold tattoo, ideal for long-term medical monitoring — it’s already so comfortable that people forgot they were wearing it.

Most skin-based interfaces consist of electronics embedded in a substance, like plastic, that is then stuck onto the skin. Problem is, the plastic is often rigid or it doesn’t let you move and sweat. In a paper published today in the journal Nature Nanotechnology, scientists used a material that dissolves under water, leaving the electronic part directly on the skin and comfortable to bend and wear. Twenty participants wore it on their skin for a week without problems. They didn’t get itchy or irritated, and the wearable didn’t break.

There’s been a lot of interest in skin-based interfaces that remotely control a phone or turning skin into a touchscreen for a smartwatch. Those are cool tricks, but health monitoring is higher priority. Almost all kinds of medical monitoring — from measuring brain signals or heart beats — means putting electrodes on the skin. This is fine for the lab, but not convenient if you need to continually monitor these vital signals at home.

This new system uses a mesh made of a material called polyvinyl alcohol that’s already used in contact lenses and artificial cartilage. First, the scientists used electrical force to created charged threads of the material. (This is called electrospinning.) These threads were coated in gold to make them more electrically conducive. You put the entire thing on skin — in this case, the hand — and spray on some water. The polyvinyl alcohol disappears, but the gold threads are still there, and it can be used to power a LED light, or transmit data to a laptop.

There’s a lot of potential here, but the downside of the sensor being so comfortable is that it’s also delicate and might not be durable enough for the long-term. So you win some, you lose some — but having gold electronics right on the skin sure beats heavy straps or ugly caps.

  6. I have been searching for the right adjective to describe this breakthrough in Nanotechnology but it hasn't been possible.

    Just waiting for scientists to create a human being that can leave for over 200 years on earth

  7. There are actually more advanced shit that's already been invented that his piece of tool is no way close to, Nigeria is a long way behind the deam clock,we should wake up.

  8. If only we can change our mind set and perspective, then we will get there someday.

    The change that need should start from us and our old men should give way for the youths to showcase their talents.
