Who Invented Self Heating Clothes?

Before answering the question under discussion, why was a self-heated jacket invented, let’s have a sneak peek at who invented it.

In 1912, a physician named Dr. Sidney I. Russel invented the first-ever electric blanket. As the name suggests, an electric blanket comes with a built-in electrical device placed on top of the bedsheet.

The primary purpose of Dr. Sidney for creating an electric blanket is to keep the sick patients warm. Using an insulated metal tape, he covered the electrical wires to create the first-ever self-heating blanket.

In the beginning, the electric blanket came in the form of an underblanket placed under the bed. An underblanket is the one that goes underneath the bed covers to offer heat from below.

The commercial production of the self-heating blankets was officially commended in the 1920s for the patients with weakened lungs admitted to tuberculosis sanatoriums. A British company named British Thermega Underblankt started manufacturing electrical under blankets.

However, around 17 years later, over blankets were introduced in the United States later in 1937 to cover the sleeping people from the top like the conventional blankets. In the 1970s, another version of the self-heating blankets was introduced in which warm water circulated within the coils to create warmth.

With further advancements in technology, the manufacturers started incorporating different features such as automatic temperature control and safety thermostats in the electric blankets. It was George Crowley who invented a heating blanket controlled via a thermostat in 1930.

During World War II, manufacturers researched electrically heated suits designed to keep the fighter pilots warm. As a result, they improved the safety features and made the suits thinner.

Fast forward to the 2000s,  the clothing industry incorporated the above concepts to design electrically heated jackets.

A heated jacket is essentially an outdoor garment serving as the outermost layer to offer you desired protection from chilly winds and snow. It’s certainly in demand for outdoor winter sports, including skiing, winter biking, hiking, trekking, etc.

One of the most significant advantages of a heated jacket is the temperature adjustment according to the wearer’s requirement and outside temperature. A heated jacket comprises the following primary components:

  • A garment body with a weather-resistant and waterproof exterior
  • Heating panels
  • Temperature control settings
  • USB cable to connect to an external power bank

As explained earlier, a heated jacket works on the same principle as the heated electric blankets. The manufacturers assemble electrically powered heating zones between the fabric while offering a USB connection to the external battery or power bank.

Next, the electrical current passes through the small copper wires to generate heat. You should know that heat is usually the wasted energy of the electrical circuits. On the contrary, it plays the primary role in the operations of the self heating jackets.

The tiny wires spread all across different heating zones of the jacket to ensure uniform heat distribution throughout the body. Furthermore, these smart jackets come with temperature control settings which you can easily adjust according to your heating preference.

You don’t need to worry about getting an electric shock as these smart jackets include an internal thermostat. If the temperature overshoots the desired settings, the integrated safety feature automatically turns off the jacket to prevent any permanent damage to the internal circuitry.

On the downside, any damage to the electrical wires can harm the entire heating system of the jacket.

Mechanism of a Heated Jacket

The manufacturers face the two primary challenges while designing a self heating jacket:

  • Cost
  • Weight
  • Flexibility
  • Versatility

Many heated jackets comprise carbon fiber that offers the desired freedom of motion. Usually, these fibers are woven into the heating elements to serve the following purposes:

  • Protection of the heating elements
  • Heat distribution

The manufacturers carefully integrate the conductive threads and the circuitry within the jacket fabric without compromising the comfort level and, of course, the stylish appearance. 

The next important question is how long the heated jacket offers warmth. The answer depends on the selected heat setting. A premium-quality jacket lasts for nine to 11 hours on the low-heating model and six to eight hours on a medium heat setting. Lastly, a heated jacket keeps you warm for one to three hours on the highest heat setting.

Furthermore, many advanced heated jackets allow the wearers to recharge their smartphones on the go.

You should know that an electrically-heated jacket is multi-purpose winter wear that you can wear as a regular jacket after removing the battery. Hence, you can wear a heated jacket as a regular garment all year long.

Why Use a Heated Jacket?

Most of the self heating jackets are designed for the following purposes:

  • Outdoor door cold-weather sports
  • Downhill skiing
  • Winter biking
  • Trekking
  • Hiking
  • Snowmobiling
  • Construction workers
  • Carpenters
  • Health workers
  • Casual wear

Keeping yourself warm is an essential human requirement. However, it’s a primary concern, especially for those working outside in cold temperatures, as it can lead to life-threatening risks, such as hypothermia and frostbite.

People who work outdoors include construction workers, baggage handlers, snow cleanup teams, police officers, firefighters, etc. According to OSHA, all outdoor workers deal with cold stress, including chilly winds and low temperatures that lead to the heat removal from the human body.

Inadequate and improper dressing is one of the significant risk factors for cold stress. That’s why OSHA recommends protective clothing for all the outdoor laborers working outside under 4C degrees or 39.4F degrees.

Wearing a proper lightweight heated jacket improves the overall productivity and efficiency irrespective of the lower temperature. Furthermore, the jackets with water-resistant outer coating offer protection against rain and snow, thus minimizing all the environmental hazards.
