Known For
Myoelectric Prosthesis
Muscle signal sensors (EMG) control motorized joints1960s–present$25,000–$75,000Most common powered prosthetic, sensors detect muscle contractions in residual limb, gripping and releasing objects
Running Blade (Flex-Foot)
Carbon fiber J-shaped spring stores and releases energy1980s–present$10,000–$30,000Oscar Pistorius made them famous, Paralympic sprinting, debate over competitive advantage vs. able-bodied runners
Body-Powered Prosthesis
Cable and harness system activated by shoulder/body movement1940s–present$5,000–$15,000Workhorse of prosthetics, hook or hand terminal device, reliable in dirty environments, no batteries needed
Cosmetic (Passive) Prosthesis
Silicone shell matching skin tone, no active functionAncient–present$3,000–$10,000Restores appearance without function, hyper-realistic silicone skin, custom-painted veins and freckles, psychological benefit
Bionic Hand (i-Limb / bebionic)
Multi-articulating motorized fingers with pattern recognition2007–present$30,000–$100,000Individual finger control, 36 grip patterns, smartphone app customization, closest to natural hand movement
Osseointegrated Prosthesis
Titanium implant directly into bone, no socket needed1990s–present$50,000–$100,000+Eliminates uncomfortable socket, direct skeletal attachment, better proprioception feedback, surgical implantation required
3D-Printed Prosthesis
Custom-printed plastic/nylon, often mechanical2013–present$50–$500e-NABLE volunteer network, affordable for children who outgrow prosthetics, superhero-themed designs, democratized access
Microprocessor Knee (C-Leg / Genium)
Sensors + processor adjust resistance in real-time1997–present$40,000–$100,000Otto Bock's C-Leg revolutionized above-knee walking, adapts to stairs/slopes, stumble recovery, near-natural gait
Targeted Muscle Reinnervation (TMR)
Nerves rerouted to remaining muscles for intuitive control2002–present$50,000+Thought-controlled prosthetics, surgically transferred nerves create new control signals, DARPA-funded research
Sensory Feedback Prosthesis
Electrodes provide touch/pressure feedback to user's nerves2014–presentExperimentalUsers can feel objects and textures, EPFL and Cleveland Clinic breakthroughs, closing the sensory loop
Hydraulic Ankle-Foot
Hydraulic actuator adjusts ankle angle for terrain2010s–present$15,000–$40,000Adapts to hills and stairs automatically, more natural walking on uneven ground, Blatchford's Elan foot
Activity-Specific Prosthesis
Custom attachment for sports, music, cooking, etc.1990s–present$2,000–$20,000Swimming fins, guitar pick holders, rock climbing hooks, cycling adaptors, adaptive sports revolution
Neural Interface / Brain-Controlled
Brain implant or EEG cap translates thought into movement2010s–presentExperimental (research only)DARPA's Luke Arm, Neuralink ambitions, paralyzed patients moving robotic arms with thoughts, sci-fi becoming real
Powered Exoskeleton Lower Limb
Motorized leg frame with sensors for walking assistance2010s–present$70,000–$150,000ReWalk and Ekso Bionics, paraplegics walking again, FDA-approved for home use, Iron Man comparisons
Silicone Partial Hand Prosthesis
Flexible silicone restoring missing fingers with passive grip1990s–present$3,000–$8,000Fills gap for partial hand amputees, realistic finger restoration, functional passive grip, often overlooked category
