USB Powered Paper Circuits: An Alternative to Coin Batteries (2024)
Coin batteries are great for powering paper circuits, but they can be costly — both in terms of expense and environmental impact.
USB power is a great substitute for coin batteries if you need more power, want to leave a project turned on, or don’t want to keep switching out batteries. It’s also useful for creating collaborative projects that combine many small circuits into a larger display.
In this tutorial, designed for people with advanced electronics skills, we will show you how to safely substitute USB power for coin batteries, to help you power your circuits more sustainably.
We’ll also show you how to transform hardware from your junk drawer (such as old phone chargers and cables) into a portable, sustainable method for powering your paper circuit projects.
USB Powered Paper Circuits: An Alternative to Coin Batteries

In conclusion, the article "USB Powered Paper Circuits: An Alternative for Coin Batteries" is a valuable resource for individuals with advanced electronics skills who seek sustainable and efficient power solutions for their paper circuit projects. The incorporation of USB power not only addresses cost concerns but also aligns with the growing emphasis on environmentally conscious practices in electronics.
USB power is stronger than a coin battery (5V vs 3V and more current available). As a result, a USB powered circuit will have brighter LEDs. USB power is strong enough to power many devices that a coin cell battery cannot, such as motors and larger microcontroller circuits (such as a Chibi Chip).
Every circuit needs a power source. For paper circuits, a coin-cell battery is perfect because it's small and flat. We use CR2032 batteries, but any 3V coin cell battery will work.
USB power is a great substitute for coin batteries if you need more power, want to leave a project turned on, or don't want to keep switching out batteries. It's also useful for creating collaborative projects that combine many small circuits into a larger display.
What are Paper Circuits? A paper circuit is a low-voltage electronic circuit that is created on paper or cardboard using conductive copper tape, LEDs and a power source such as a coin-cell battery.
Carbon nanotubes used to construct Paper Batteries are costly.Inhaling the Paper Battery will Damage the lungs. So, it is hazardous to human health. Cellulose has insufficient shear strength, so the paper Batteries have low power, and they can tear easily.
Using paper gives the battery a great degree of flexibility. The battery can be bent or wrapped around objects instead of requiring a fixed casing. Also, being a thin, flat sheet, the paper battery can easily fit into tight places, reducing the size and weight of the device it powers.
A paper circuit is a circuit made on a sheet of paper rather than using wires and crocodile clips. You can use adhesive copper tape to connect up components and simple coin batteries to provide the power. It's probably best to draw out your circuit with pencil first (but not essential).
Many paper circuit-specific components such as LED stickers, boards, or modules have built-in resistors. If creating your own paper circuit components with off the shelf LEDs, you may need to add resistors to your circuit to account for different voltage requirements.
It is a conductive material but is available in two common types, known as conductive and non-conductive. Conductive tape can conduct electricity on both the top and bottom of the tape, whereas non-conductive copper tape is only conductive on the one side.
use LiFePO4 cells in series to achieve a nominal voltage of 12.8V. One of the great advantages of lithium batteries over lead acid batteries is the fact that they maintain their output voltage above 12V much, much better than lead acid.
Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold.
- Paper battery is a new concept of manganese battery developed from applying the technology of thin film printing, and has a flexible and thin physical characteristics. - It is a battery suitable for equipments that consume a microamper current.
