What are Technical Springs?

Technical springs are devices that store and release mechanical energy. Manufacturers make them from various materials, including steel, titanium, and nickel alloys, and they produce them in many shapes and sizes. Engineers use technical springs in various applications, including aerospace, automotive, robotics, medical devices, and energy storage and harvesting systems.

Definition of technical springs

People usually define technical springs as springs with a specific technical application. Experts can categorize them into various types based on their shape or mode of operation.

Some common types include:

• Torsion Springs: These springs store energy when twisted around their axis. They are often used in watches or other mechanical devices.

• Compression Springs: Springs absorb energy when compressed and release it when someone removes the force. People commonly use them in car suspensions.

• Tension Springs: These store energy by stretching along their axis. Examples include bungee cords.

• Constant Force Springs: These provide constant force throughout their travel distance. They can be found in retractable seat belts or tape measures.

Types of technical springs used in energy storage and harvesting applications

In energy storage and harvesting applications, two key types of technical springs stand out: mechanical batteries (also known as mechanical capacitors), which use mechanical deformation to store electrical charge; piezoelectric transducers that convert mechanical stress into electrical charge through the process known as the piezoelectric effect. Mechanical batteries can have higher power densities than traditional electrochemical batteries and longer lifetimes due to less degradation over time. On the other hand, Piezoelectric Transducers can generate electricity from various mechanical sources, such as vibration, strain, or pressure, to power electronic devices without external energy sources.

Another important aspect in technical springs is the materials used. For example, Nitinol (an alloy of nickel and titanium) has shape memory properties and elasticity, making it useful for applications where temperature changes or shape deformation may occur.

People also commonly use titanium alloys because they have a high strength-to-weight ratio, resist corrosion, and are biocompatible. Engineers are exploring various composite materials, including carbon fiber, for use in these systems because they can store energy efficiently without occupying much space.

Energy Harvesting Applications

Overview of Energy Harvesting Systems using Technical Springs

Energy harvesting systems increasingly use technical springs to convert mechanical energy into electrical energy. These systems harvest mechanical vibrations and convert them into electrical energy through the piezoelectric effect, which generates a voltage when subjected to mechanical stress.

Technical springs are critical components of such systems since they act as transducers that convert the vibrations into electrical signals. One important application of piezoelectric generators that use technical springs is wearable technology, which can generate electricity from body movements.

For instance, a person wearing a smartwatch could generate electricity from their wrist movements and then use it to power the watch or other electronic devices. These devices could also potentially power medical implants such as pacemakers and hearing aids, eliminating the need for battery replacements.

Advantages and Disadvantages of Using Technical Springs for Energy Harvesting

One significant advantage of using technical springs for energy harvesting is their ability to operate under low-frequency excitation conditions. This enables them to harvest useful energy from everyday sources such as footsteps or ambient vibrations in buildings or vehicles.

Furthermore, technical springs offer high power density and have high fatigue resistance due to their relatively small size. Technical spring-based energy harvesting systems also have some disadvantages.

The amount of harvested energy typically falls short compared to conventional power sources like batteries or solar panels. Moreover, technical spring materials can often be brittle. They are prone to failure after prolonged use under repeated loading cycles.

Examples of Energy Harvesting Systems Using Technical Springs (e.g., Piezoelectric Generators)

Several examples of piezoelectric generators utilize technical springs for efficient mechanical-to-electrical energy conversion. For instance, developers are creating a piezoelectric floor tile to harvest energy from pedestrian footsteps in high-traffic areas such as shopping malls, airports, and train stations.

The tile comprises a series of thin piezoelectric plates coupled with technical springs that amplify the deformation of the plates when a person walks over them. Another example is the development of self-powered sensors for structural health monitoring in buildings.

These sensors utilize technical springs and piezoelectric materials to generate electricity from the vibrations caused by nearby construction or natural disasters such as earthquakes. This technology has the potential to provide real-time data on building conditions without requiring external power sources or replacing batteries.

Technical springs are crucial components in energy harvesting systems that convert mechanical vibrations into electrical energy. This technology presents challenges. However, it holds tremendous potential. It can be used in wearable electronics, smart home automation systems, and other applications.
