Adidas released its Micropacer shoes two years earlier in 1984, which recorded distance, running pace, and calories burned through a microsensor on the left toe, and it displayed the data on a screen on the shoe’s tongue.

The company is refocusing its business, Mr. Bozotti said, and expects growth in 2013 to be driven primarily by sales of devices in its imaging, analog and microsensor, and microcontroller businesses.

The microsensor devices monitoring a medical package containing a human organ on its way for transplant, require a battery.

Measuring just ¼ cubic inch, these tiny robots carry sophisticated gear including a camera, microphone or a chemical microsensor.

But even today's most impressive devices may soon seem downright primitive, thanks to relentless progress in microsensor science.
