Low power indoor devices Low power indoor devices

  • Today: batteries

– Limited lifetime – Cost of replacing battery > cost device Battery waste not environmentally friendly – Battery waste not environmentally friendly

  • Tomorrow: energy from renewable resources

in the environment (heat, motion, light) ( , , g )

⇒ “infinite” lifetime
