The Power of Deep Sleep#

By keeping microcontrollers in sub-microampere deep sleep states and only waking for milliseconds to sample sensors, IoT hardware achieves decade-long battery autonomies.

Everyday Analogy#

A sleeping bear hibernating through winter, slowing down heartbeats and metabolism to conserve energy until warm spring arrives.

Practical Applications#

  • Battery-powered wireless door sensors lasting five years on a single coin cell
  • Remote wildlife tracking collars operating off micro-solar harvesters
