The newly Harvard-created Exoskeleton allows many people to find the support they need in every day life. The lightweight, battery powered machine can be used to support the wearer and allow them to carry heavier objects over longer distances. It propels the legs forward without effecting the normal human gait. 
The exoskeleton mimics the human limb by using nylon mesh, cables, and sensors to connect directly to muscles, tendons, and nerves. Although it cannot help people who have lost full usage of their legs, it can still greatly improve the lives of some. For example, those who encounter muscle weaknesses from strokes find the research of exoskeletons quite useful. The machine can help weak people walk more easily or help healthy people carry heavier objects. The potential for this machine varies from supporting soldiers, assisting the elderly, rehabilitating children or adults, and easing the physical struggles of firefighters or paramedics. Although the machine is only a recent protocol, the exoskeleton is being largely researched and has many updates before its released into the public.
