Massachusetts Institute of Technology (MIT) engineers in collaboration with South Korean cosmetic giant Amorepacific Corp. have created a chip-free, wireless electronic “skin” for sensing and transmitting vital medical signs minus larger, clunkier chips or batteries in most smartphones. MIT postdoc Jun Min Suh explained any change to the skin’s conditions, such as an accelerated heart rate, affect the sensor’s mechanical vibrations, generating an electrical signal that automatically transmits medial data to the consumer.
