-It should be noted that the circuit designed above is the simplest implementation: more complex implementations (such as [[Federated Energy Storage]]) are possible, but beyond the scope of this article.+It should be noted that the circuit designed above is the simplest implementation: more complex implementations are possible, but beyond the scope of this article.
  
 Regardless of the energy configuration used, however, it is likely that processing will consume more power than is available in a single cycle: as a result, an intermittent device will often save (checkpoint) the current system state periodically, in order to resume as needed after power loss until the processing is complete. Regardless of the energy configuration used, however, it is likely that processing will consume more power than is available in a single cycle: as a result, an intermittent device will often save (checkpoint) the current system state periodically, in order to resume as needed after power loss until the processing is complete.

-Total power is considerably more constrained compared to a traditional device: for example, a traditional device may use its MCU to calculate whether a minimum voltage threshold has been reached, but in an intermittent circuit using the MCU in this fashion will often consume too much of the available power to be viable.  Intermittent circuits must be designed not only around intermittent power suppliesbut lower ones as well.+Capacitors can store only a fraction of the energy that a similarly-sized battery can.  This means that power, when it is available, will often be considerably limited and require unique approaches to tackling certain problems that are not faced by battery-powered devices.
