How Do Exoskeletons Work?

Exoskeletons tend to be the stuff of dreams, especially for fans of science fiction. There are many examples of how this device is used in fantastic settings, in some of our favorite pieces of sci-fi entertainment. In Aliens, the heroine fights a gigantic, acid-spewing Alien queen with the use of a power loader exoskeleton. In all of the Iron Man movies, Tony Stark uses a variety of exoskeleton suits to save the day. In the billion-dollar grossing Avatar movie, an amplified mobility suit/ exoskeleton is used by the bad guy mercenaries to take on the Na’vi, and of course who could forget the robotic exoskeleton that is Robocop?

Such futuristic outfits are fantastical in their idea of what exoskeletons would eventually look like, and what they might be used for. But these robots are not actually fantasy. In the current day, exoskeletons do exist and provide an important service to their users. Exoskeletons are wearable devices that work hand-in-hand with their operators. They are usually used to augment, reinforce, or restore performance for a human wearer. This is done by being placed on the body, essentially acting as an amplifier to their movements.

Where do exoskeletons come from?

These devices are often made out of metal or carbon fibers (rigid materials) or are composed of soft and elastic parts. Exoskeletons were first invented in the 1960s by General Electric, with the creation of a device called the Hardiman. The first exoskeleton was a large full-body device that was designed to augment the wearer’s strength and enable the lifting of heavy objects, whilst reducing fatigue. At the end of that same decade, gait-assistance exoskeletons were created at the Mihajlo Pupin Institute in Serbia. By the time the 1970s came around, another gait-assistance exoskeleton was created at the University of Wisconsin-Madison.

Since then exoskeleton innovation has hit a variety of technological heights. Towards the end of the 2010s, a variety of lightweight military exoskeleton prototypes had been developed. The goal for these was to augment a user’s strength and endurance. Post-2010, there were several gait-assistance and restoration exoskeletons that were introduced to the public. An example of this is Ekso Bionics’ various robotic exoskeleton, produced by this industry leader, based in the United States.

How does the exoskeleton work?

To answer the question of how such devices work, we must first begin by discussing the frame of an exoskeleton. Depending on what materials went into making them, they are often lightweight and allow quite a degree of freedom when it comes to movement. The frame goes around the user’s body, or part of their body, depending on the type being used. In some cases, the exoskeletons can contain sensors that are used to monitor and then respond to a person’s movements.

What do they run on?

Exoskeletons require different types of power sources to help them operate. They can be either motorized or mechanical, while others run on electricity. Some exoskeletons don’t require any electricity and offer more freedom for a user. One useful example of seeing how these work is in the EksoUE suit. The EksoUE is an exoskeleton that assists patients who have limited mobility or limb injury in the upper body. The exoskeleton technology works with a patient’s affected shoulder and arm during his or her rehabilitation. This device is a wearable upper-extremity type of medical exoskeleton.

This device has interchangeable springs, which allows for different powered active-assisted function movement. The device’s operation is based on the patient’s strength, endurance, and the weight of their limb or extremity. This is often how most other exoskeletons work, as they are based around the user who is operating them. In the case of the EksoUE, how the exoskeleton operates is based on how the patient utilizes the device. These devices are often used for occupational or physical therapy sessions. This helps to allow for longer and more high-intensity therapy sessions and is a huge assist in increasing muscle activity, and motor functions.

Scientific Ways to Make Yourself Look and Feel More Attractive

Feeling attractive is more psychological than physical. Believe it or not, there is a science to attractiveness that goes beyond genetics. These are some scientific ways to make yourself look and feel more attractive.

Wear the Right Scent

Fragrances have a powerful impact on the brain. Some scents can trigger positive emotions and bring out good memories. Confidence is directly related to positivity, so it makes sense to wear a fragrance associated with happy times. Wearing a subtle amount of an attractive fragrance makes one more attractive to others, which further increases confidence and inspires an attractive body language.

Dress in Red

A pop of color in an outfit is a great way to attract attention. Wearing red, the color of passion, not only attracts attention but it also makes people see the wearer as more attractive. Studies have shown that men perceive women to be more attractive, even sexier when wearing red clothing or lipstick. The color itself is what draws attention, and the feeling of being noticed is what leads to feeling more confident.

Makeup and Eyebrows

Well-maintained eyebrows go a long way toward attractiveness. Get in the habit of regularly shaping eyebrows either at home or with an esthetician and know how to fill in sparse areas and create a defined arch. Many cultures find bold eyebrows that create facial contrast as highly attractive.

Women should wear simple makeup and pop it with colorful lipstick and played up eyes. Wearing mascara opens the eyes, lengthens lashes, and defines the eyes. Applying magnetic eyelashes is a quick and simple way to create an attractive look. Glamnetic’s magnetic eyeliner and mink eyelashes can be reused multiple times. Simply remove lashes with olive oil or coconut oil and place them back in their magnetized tray to keep their shape. Glamnetic carries a range of eyelashes in different lengths and colors to help women achieve any desired look.

Stand Tall

Body language and posture play a big role in attractiveness. Taking a dominant stance or power pose increases confidence and signals to others a sense of power. Lazy or standoffish body language, like hunched shoulders or crossed arms, is less attractive. Standing tall with shoulders back and arms relaxed gives an approachable vibe and attracts others.

Those with strong jawlines are perceived as more attractive. Women who see men with their chins up perceive them as assertive and confident. Be conscious of holding the head up high in a way that defines the jawline and slims the neck.

Don’t Forget Sunglasses

Wearing sunglasses adds a sense of mystery to any look and boosts facial symmetry. Just like clothing, it’s important to wear the right sunglasses that complement face shape. Rounder faces do better with angular frames while angular faces do better with rounder frames. The right style of sunglasses makes the face look more proportionate which increases attractiveness.

Get an Adrenaline Rush

A healthy way to boost attractiveness is to exercise. Exercising causes the brain to release endorphins that lower stress levels, give a sense of well-being, and boost confidence. These factors not only make one feel more attractive, but others also notice as well. Another way to be more attractive is to participate in extreme activities that cause an adrenaline rush. Women tend to find men who do risky activities, like extreme sports, more attractive.

Well-being starts from within and sometimes a little help goes a long way. Complement exercise with daily CBD usage to increase feelings of calm and relaxation. The CBD Insider features in-depth product reviews from major CBD brands.

Is CBD Good for Bipolar Disorder?

From the production of easy-to-manufacture rope to drink products packed with proteins, the cannabis industry is receiving more visibility as it continues to gain popularity and exposure. One of its more popular ingredients, however, has become the next big health kick in a relatively short amount of time. Named Cannabidiol (CBD), this chemical found within certain hemp flowers is said to be useful as a remedy for a wide variety of health problems, including mental health conditions. 

As a result, some parents may turn to CBD in an attempt to treat personality disorders in teens or issues that they may be facing themselves. But is this safe? If you have been using CBD for a personality disorder such as obsessive-compulsive disorder or borderline personality disorder, or a mood disorder such as bipolar disorder, let’s dive deeper into the interactions between this chemical and the brain. 

What Is CBD And What Does It Do? 

CBD is a chemical found within the hemp plant that is said to relieve anxiety and improve brain function. Belonging to a group of chemicals known as cannabinoids, which are naturally produced within the body but can also be introduced into the body through certain hemp strains, CBD is very similar in nature to the popular THC, with the exception that it does not produce any psychoactive effects. 

Many turns to CBD as a way to alleviate their health problems, whether those be pain-related or mental health-related, due to the fact that CBD is said to produce the same types of benefits produced by THC. However, it is important to note here that research is scarce. Although it is believed to help a variety of conditions, we still need further proof. 

How Would CBD Impact Bipolar Disorder (And Why Do Many Believe It Can)? 

The belief that CBD can serve as useful alternative treatment option for bipolar is a result of the belief that marijuana could work for certain mental health conditions. Even in this grouping, research can be contradictory, with some research stating that marijuana serves to boost mood and improve the outlook of those struggling with bipolar disorder while other research suggests higher suicide rates and worsening symptoms as a result of marijuana use. 

This research is important when it comes to further studies regarding CBD as it is widely accepted that CBD would, theoretically, produce the same results. This type of thinking may also support that CBD could be beneficial as it produces no harmful psychoactive effects in the process. 

Due to the lack of research at the time of writing, there is no strong support to back either side of these claims. In fact, there are some sources that state that CBD is actually ineffective, producing no benefits for those struggling with bipolar disorder. Some users of the substance who do feel that it can help them believe that it helps them feel more calm or relaxed when a manic episode begins manifesting. 

Although it may or may not do any good, the beneficial aspect of this chemical compound is that it does not produce the serious consequences that you can see in those with bipolar who choose to use cannabis to target their symptoms. 

So, is CBD good for bipolar disorder? There is no conclusive evidence to say whether or not CBD is going to help you regulate your moods and make it easier for you to handle manic and depressive episodes. 

That said, further research may reveal that improvements in mood can be made with this substance, and using it in the meantime should not produce any ill effects. Whether you decide to use full spectrum cbd capsules or other products, make sure to speak with your doctor and follow the directions.
