We are going to wear computer using Digital Jewellery

Digital Jewellery  is a technology which is developed by IBM (International Business Machines). The main intention of IBM is to solve problems like forgetting passwords, pins etc.. with fashion technology. So that we can make technology as our daily ware jewellery like rings, chains with wireless networking system. Let us see more about this technology. 

Lets see an example :

Here are the pieces of  computerized phone in the form of jewellery 

 Functions of each piece shown in figure :

  • Earrings – speakers embedded into these earrings will be the phone’s receiver.
  • Necklace – Users will talk into the necklace’s embeddedmicrophone.
  • Ring – Perhaps the most interesting piece of the phone, this “magic decoder ring” is  equipped  with light-emitting diodes (LEDs) that flash to indicate an incoming call. 

Java Ring

  • The Java Ring is snapped into a reader, called a Blue Dot receptor, to allow  communication between a host system and the Java Ring.
  • The Java Ring is a stainless-steel ring, 16-millimeters (0.6 inches) in diameter, which houses a 1-million-transistor processor, called an iButton.
  • The ring has 134 KB of RAM, 32 KB of ROM, a real-time clock and a Java virtual machine, which is a piece of software that recognizes the Java language and translates it for the user’s computer system.

It seems that everything we access today is under lock and key. Even the devices we use are protected by password we use java ring for this purpose.

 Highlights of Java Ring

  • Runs Java better (plus portions enhance Java Card 2.0)
  • Careful attention to physical security (rapid zeroization)
  • Durability to stand up to everyday use
  • High memory capacity (up to 134K bytes NV SRAM)
  • Retail connectivity to 250 million existing computers (less if designed-in before manufacturing)


  • By the end of the decade, we could be wearing our computers instead of sitting in front of them.
