  3. 3. Which technologies popped up within the last years? ???????????? Smart Textiles: conductive, functional, shape remebering, sensing Electronics: wireless technologies & Software: mobile computing, µC-platforms cloud applications touch screens Materials: Nanotubes, Motors, Gearing, CAD/CAM thin-film systems 3D printing Regulatory: 14791, 60601-1.1 edII(I), 60601-2-10 edII(I), 13485, 62304, 82304, 10993, CE, FDA, C-tick, Canadian registration… TechNatives | Michael Russold | Okt. 2013 3
  4. 4. (Why) do they matter? Do they matter in our field???? Medical Device development 1. You don‘t know what you don‘t know 2. Regulatory Red Tape can be avoided by being smart 3. Work with experienced partners with trusted relationships only 4. Documentation, Documentation and more Documentation TechNatives | Michael Russold | Okt. 2013 4
  5. 5. How does mobile, wearable, smart tech impact the audience? hopefully never, in my field How do you apply the technologies in your field of business? Case studies TechNatives | Michael Russold | Okt. 2013 5
  6. 6. The most famous prosthesis of them all What the media presents TechNatives | Michael Russold | Okt. 2013 © Otto Bock HealthCare 6
  7. 7. Control and Mechanics of Prosthetic Devices Human arm vs. prosthetic device upper extremity human Commercial prosthesis •  Human anatomy •  Mechanics – 20+ DOF (incl. hand) •  perfect control – maximum 4-6 DOF •  Control – life-long learning phase – sequential control – proprioception – pattern recognition with simultaneous control emerging – Feedback – force – temperature – humidity – no proprioception – no Feedback, although field of interest in research – …............
