EXISTING KNOWLEDGE AND TECHNOLOGY GAP
New types of actuators are currently studied such as shape memory alloys (SMA), electro-rheological fluids, magneto-active transducers, single crystal piezoelectric ceramics, carbon nanotubes, electrostatic, and electroactive polymers (EAPs). Because of this characteristic, they are often referred to as “artificial muscles”. SMAs have been proposed as artificial muscles because of their relative non-toxicity, reasonable cost, very large forces per unit area, high strain rates and relatively large deformations.
To investigate the feasibility of the use of Shape memory alloy (SMA) as wearable actuators for the development of sEMG controlled orthoses.
