Frequently Asked Questions

The Penciling Triboelectric Nanogenerator has been found to be a promising renewable energy source. Our tests have shown that the generator is capable of producing up to 5 volts of electricity. In our test it can light up diode light, it can power a small circuit or you can store the generated energy for future use.

There could be several reasons why you are unable to store energy in a rechargeable battery. Here are a few possibilities:

1. The battery may be damaged or faulty: If the battery is damaged or faulty, it may not be able to hold a charge. This can happen if the battery has been exposed to extreme temperatures or if it has been dropped or otherwise physically damaged.

2. The battery may be incompatible with the device: If you are trying to charge a battery that is not designed for your device, it may not be able to hold a charge. Make sure that you are using the correct type of battery for your device. Try using small type of batteries when you're producing small voltage to prevent energy from decaying.

3. The charging process may be incorrect: If you are not using the correct charging process for your battery, it may not be able to hold a charge. Make sure that you are following the manufacturer's instructions for charging the battery.

4. The battery may be reaching the end of its life: Rechargeable batteries have a limited lifespan, and they will eventually lose their ability to hold a charge. If your battery is old, it may be time to replace it.

The choice of material for the contact surface of a Penciling Triboelectric Nanogenerator (P-TENG) is an important factor that can affect the efficiency and performance of the device.

While paper is a common material used for TENGs due to its availability and low cost, there are other materials that can be used as a substitute depending on your specific application requirements.

Here are some alternative materials that you can consider using as a substitute for paper in your penciling TENG:

1. Metal foil: A thin metal foil such as aluminum or copper can be used as the contact surface for your TENG. Metal foils have a high conductivity and can generate a significant amount of electrical charge when rubbed against a suitable material.

2. Polymer film: A polymer film such as polyethylene or polypropylene can be used as the contact surface for your TENG. Polymer films are lightweight, flexible, and can generate a high amount of electrical charge when rubbed against a suitable material.

3. Textile fabric: A textile fabric such as cotton or polyester can be used as the contact surface for your TENG. Textile fabrics are soft and flexible, making them suitable for wearable applications.

4. Silicone rubber: Silicone rubber is a flexible and durable material that can be used as the contact surface for your TENG. It has good electrical insulation properties and can generate a high amount of electrical charge when rubbed against a suitable material. When selecting a substitute material for paper, it is important to consider factors such as the triboelectric properties of the material, its durability, flexibility, and cost.

You may need to experiment with different materials to find the one that works best for your specific application.

To increase the efficiency of your penciling TENG, you can try the following techniques:

1. Increase the contact area: The amount of electrical charge generated by a TENG is proportional to the contact area between the two materials. Therefore, increasing the contact area between the pencil and the paper can improve the efficiency of your TENG.

2. Increase the pressure: The amount of electrical charge generated by a TENG is also proportional to the pressure applied between the two materials. Therefore, you can try applying more pressure between the pencil and the paper to increase the efficiency of your TENG.

3. Optimize the materials: The choice of materials used in your TENG can also affect its efficiency. You can experiment with different materials to find the combination that produces the highest amount of electrical charge.

4. Use multiple TENGs: You can improve the overall efficiency of your TENG by using multiple devices in parallel or series. This will increase the total amount of electrical charge generated by the system.

5. Use an external circuit: It is important to note that a TENG produces an alternating current (AC) that needs to be rectified to be useful. By connecting your TENG to an external circuit that includes a rectifier, you can improve the efficiency of your device.

By implementing these techniques, you can increase the efficiency of your penciling TENG and generate more electrical energy from mechanical motion.
