Mission!

 RADIO6ENSE  is  a  spin-­‐off  of  the  University  of  Roma  "Tor  Vergata",  aiming  at  developing  short-­‐range  distributed  RFID  sensing  technology  to  discreetly  measure  and  quanAfy  our  interacAon  with  things  and  with  the  surrounding  spaces.    RADIO6ENSE's  products  and  services  provide  the  last  10  meters  of  the  emerging  Internet  of  Things,  enabling  Cloud  Services  to  interact  with  the  real  World.    RADIO6ENSE  offers  hardware  and  soIware  soluAons  addressed  to  System  Integrators,  Engineers,  Consultancy  companies,  Public  and  Private  Agencies,  as  well  as  End  Users  willing  to  introduce  the  RFID  Sensing  Technology  inside  their  own  processes  and  work-­‐flows.

•  The   Wearable   Tags   are   passive   UHF   RFID   tags  suitable  to  operate  in  close  proximity  of  the  human  body.    

•  The   lightweight  materials  and   the  small   sizes  allow  them  to  be  placed  in  

ü  badge  necklace  ü  wallets  ü  pockets  or  pursues    ü  Smart  plasters,  wristbands,   clothes,   sport   suits  and  

garments  in  general.  

•  On   request,   RADIO6ENSE   is   available   to   customize  the   size,   material   and   the   shape   of   the   wearable  tags  according  to  the  specific  applicaAons.  

Wearable  RF  Tags  

Tags   of   different   sizes   and   shapes  produced  by  radio6ense  can  achieve  up  to   6   meters   read   range   enabling   a  robust  monitoring  in  a  4x4  m  room  with  a  single  reader.
