The goal is to have an energy source that outputs the microcontroller’s required current and voltage. While microcontrollers can often be powered by a direct or alternating current, for added security, many developers use external batteries to support necessary functions.
Additionally, batteries enable devices to go cordless. A device that doesn’t need to be plugged into a wall can be more easily transported. When using current microcontroller battery technology, there are certain limitations because a battery can only provide so much power for so long.
But the issue with these batteries is that most of these batteries are rated for 3.7 volts and a maximum of 4.2v. Now for our application we generally need either 3.3v or 5v because typical microcontrollers and sensors work on these voltage levels. So in order to get the right voltage you either need a buck converter or a boost converter.
Electrochemical microcontroller batteries only last a fraction of the time that newer betavoltaic power sources do—and they degrade from frequent usage. Our tritium battery products have been tested to last longer than two decades and perform without permanent degradation under extreme external conditions.
Corresponding technological advances must be able to sustain these new devices. This is one reason why City Labs has developed long-lasting NanoTritium™ batteries to power low-energy microelectronics. Microcontrollers cannot function without a power supply. They have no built-in battery, meaning they are powered with external sources.
