“…The vast majority of these solutions are composites based on conductive particles immobilized in an elastomer matrix. The conductive phase of the CPC may constitute of metal particles (gold [ 8 , 9 ], platinum [ 10 ], silver [ 11 , 12 , 13 , 14 ], copper [ 15 , 16 ], and nickel [ 17 , 18 ]), metal oxides (ZnO [ 19 , 20 ], Fe 3 O 4 [ 21 , 22 ], and RuO 2 [ 23 ]) carbon nanostructures (carbon black [ 24 , 25 , 26 ], graphite [ 27 ], graphene [ 28 , 29 , 30 , 31 , 32 ], and carbon nanotubes [ 32 , 33 , 34 , 35 , 36 , 37 ]) and their oxides (reduced graphene oxide [ 38 , 39 ] and graphene oxide [ 40 ]). The elastomer matrixes most commonly used are: poly (dimethylsiloxane) (PDMS) [ 9 , 20 , 28 , 31 , 35 , 41 ], TPU [ 33 , 38 , 42 , 43 , 44 , 45 ], PU [ 46 , 47 , 48 ], SBS [ 49 ,…”

Rapid growth of personal electronics with concurrent research into telerehabilitation solutions discovers opportunities to redefine the future of orthopedic rehabilitation. After joint injury or operation, convalescence includes free active range of movement exercises, such as joints bending and straightening under medical supervision. Flexion detection through wearable textile sensors provides numerous potential benefits such as: (1) reduced cost; (2) continuous monitoring; (3) remote telerehabilitation; (4) gamification; and (5) detection of risk-inducing activities in daily routine. To address this issue, novel piezoresistive multi-walled carbon nanotubes/graphite/styrene–butadiene–styrene copolymer (CNT/Gr/SBS) fiber was developed. The extrusion process allowed adjustable diameter fiber production, while being a scalable, industrially adapted method of manufacturing textile electronics. Composite fibers were highly stretchable, withstanding strains up to 285%, and exhibited exceptional piezoresistive parameters with a gauge factor of 91.64 for 0–100% strain range and 2955 for the full scope. Considering the composite’s flexibility and sensitivity during a series of cyclic loading, it was concluded that developed Gr/CNT/SBS fibers were suitable for application in wearable piezoresistive sensors for telerehabilitation application.
