Robotic Artificial Muscles Market

Robotic artificial muscles build up a sub-category of artificial muscles which are able to produce biologically stimulated motions. There is a vast range of motions that these robot systems carry out including inherent compliance, power-to-weight ratios, and many others. These types of artificial muscles have potential utilization in a wide range of applications owing to their achievements in control methods, modeling, and fabrication. They are widely used in medical devices or smart textiles. This aided the market to flourish via industrial sectors. The Robotic artificial muscles market grow with a CAGR of 17.4% by 2022-2030.

The rising prevalence of diabetes and other diseases which elevate the demand for prosthetics has significantly contributed to the market share. According to the International Diabetes Federation, in 2019, approximately 463 million adults (20-79 years) were living with diabetes; expected to rise to 700 million by 2045. Many diabetic patients have a risk of developing foot ulcers, which often lead to amputation. Also, according to the Amputee Coalition of America, vascular diseases are considered the main cause of lower limb amputation.
