Astronauts could wear a device called a vibrotactor to prevent disorientation in space. Vibrotactors are wearable gadgets that vibrate to provide orientation cues. They can help astronauts cope with spatial disorientation, which results from the lack of gravitational cues they are accustomed to using when on Earth

Researchers have found that wearable devices that provide orientation cues through vibrations can greatly enhance the effectiveness of astronaut training. In one study, participants wearing vibrotactors performed better than those who only received training. The training-only group crashed more frequently, moved around the balance point more, and accidentally destabilized themselves more often. 

The vibrating devices, or vibrotractors, provide cues via skin to the vestibular system, the apparatus in our inner ear which tells the brain the tilt of our head and helps to keep us on an even keel.

Scientists have created wearable vibrotactile devices to help astronauts stay oriented and safe in space. Astronauts usually undergo extensive training to protect themselves from disorientation

Astronauts wear several devices in space, including: 

• Spacesuits: Protect astronauts from the cold, radiation, and low pressure in space. They also provide oxygen to breathe, hold water to drink, and include a helmet, visor, and gloves. 

• Primary Life Support System (PLSS): A backpack-like device that provides the suit with pressurized oxygen and ventilation while removing carbon dioxide, water vapor, and trace contaminants. 
• Gloves: Pressurized gloves are included with the spacesuit unit. 

Astronauts also use other devices, including: 

• Pistol-grip tool 
• Robot crane 
• Trace gas analyzer 
• Safety tethers

During the launch and re-entry, the astronauts wear a partially pressurized suit and a parachute pack. The suit has a helmet, gloves, and boots which all serve as protection for the astronaut. Within the suit are bladders that automatically fill with air at reduced cabin pressures

Spacesuits are made of high-tech components that integrate with the vessel’s systems. They are made of fire-resistant Kevlar and Nomex. A single connection point on the leg of the astronaut provides vital connections for both air and power. 

Space suits are equipped with reflective coatings of Mylar that offer limited protection against radiation. However, it doesn’t guard against the solar flare, which is why spacewalks are only carried out during low solar activity. 

To cope with the extremes of temperature, most space suits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight. 

Current space suits are equipped with radio transmitters/receivers so that spacewalking astronauts can talk with ground controllers and/or other astronauts. The astronauts wear headsets with microphones and earphones. 

Space suits consist of two 16.8-volt batteries, a distribution panel, and power distribution harness. A battery weighs about 4 pounds and has 27 watt-hours of use.
