Nanotech tattoo as health monitoring device
Researchers in South Korea have developed an electronic tattoo ink made of liquid metal and carbon nanotubes that functions as a bioelectrode.
- The device could be used to send readout of the wearer's vital signs if connected to biosensors, including for instance an electrocardiogram.
- Alongside heart rates it could be used to read glucose or lactate levels for people with diabetes or sepsis.
- The monitors could in theory be located anywhere, including in patients' homes.
About Bioelectrodes and Biosensors
- Bioelectrodes are sensors used to transmit information into or out of the bodyand are mainly applied in cardiology and neurology applications.
- Surface or transcutaneous electrodes used to monitor or measure electrical events in the body.
- A biosensor uses biological molecules, tissues, organisms to measure chemical or biochemical concentrations. Biosensors can be used in many medical and non-medical applications.
- Biomedical sensors detect simple physical parameters like blood pressure or temperature to blood glucose.
- Biosensors works by changing the pH, ions, blood gases (O2, CO2 and etc.), drugs, hormones, proteins, viruses, bacteria, tumors and etc.
The Electronic Tattoo:
- The electronic tattoo ink is made of liquid metal and carbon nanotubes that can deliver vital body information.
- The ink is non-invasive and made from particles based on gallium, a soft, silvery metal also used in semiconductors or in thermometers.
- Platinum-decorated carbon nanotubes help conduct electricity while providing durability.
- When it is applied to the skin, even with rubbing the tattoo doesn’t come off, this is not possible with just liquid metal.
Verifying, please be patient.
