8 Product Development Process Production Customer Needs & Market Trends? Health Sciences Manufacturing Process Design Product Design Product Concepts Engineering

9 Goal The expected result of the project is to develop solutions for the sector of biomedicine (new medical devices) and bioengineering listed in the proposal or others proposed by Doctors

10 Partners Americas European Union Rutgers Tec de Monterrey Brescia CTI Leiria Girona Mexico United States Brazil Spain Italy Portugal

11 Exchange conditions The European Commission supports the secondments of: Italian researchers going to Brazil, Mexico and USA researchers from Brazil, Mexico and USA to Italy Researchers are divided by EU in: ER (Experienced researcher): professors, researchers, PhD, students with a Bachelor degree and 4 years of research activity. ESR (Early Stage Researcher): students with a Bachelor and less than 4 years of research activity.

12 Activities Workshops Instructor: Partners with medicine schools Specialized medical doctors Lectures Attendance by all early stage researchers and other interested public Meetings Attendance by all experienced researchers Videoconference transmission to partner sites 12

13 Activities Joint Research Projects Focus: enabling technologies for biomedical device development Design Materials Prototyping Manufacturing Processes Exchange characteristics 2 to 3 partners Early stage researchers Length: 4 to 12 months Predefined outcomes in relation to the expert seminar findings 13

14 Joint Research Projects overview

15 Titanium Sheet for Biomedical Devices As well known, the biomedical compatibility of Titanium, makes it suitable for prosthesis. Moreover, the very high customization required by patients (till one single piece batch), makes ISF very suitable for plaque prosthesis such as in oral or skull implant.

16 IF for manufacturing Ti Sheet Geometry acquisition: CT STL file generation Tool path realization Final part Part production

17 Department of information Engineering SMART PROSTHESIS: DESIGN AND TEST OF AN AUTONOMOUS SENSOR FOR FORCE MEASUREMENTS IN HUMAN KNEE IMPLANTS. M.R.H. - Mechatronics based rehabilitation at home

18 INSTRUMENTED PROSTHESIS Department of Information Engineering Realization of an autonomous sensor to be placed inside the total knee prosthesis in order to measure the in-vivo forces applied to the insert itself. i Insertion of the circuit inside of tibial polyethylene insert. MAGNETS POLYETHYLENE INSERT Information on the load distribution of the joint directly from the insert. Support in the design of orthopedic implants. Useful during the post-operative rehabilitation. 125 khz 125 ANTENNA khz MAGNETORESISTORS M.R.H. - Mechatronics based rehabilitation at home

19 INSTRUMENTED PROSTHESIS Department of Information Engineering Power supply via an external magnetic field. An inductor connected to the reading device is positioned externally to the leg and creates an electromagnetic field that allows the sensor to self-sustaining. i Benefits It does not require batteries: maintenance and replacement batteries absent, environmentally friendly solution. READOUT UNIT M.R.H. - Mechatronics based rehabilitation at home Data transmission with wireless technology at 125 khz. Benefits No need for cables: reduced size and weight, minimal impact on pre-existing structure

M.R.H. - Mechatronics based rehabilitation at home FORCE [N] FORCE [N] Sinusoidal Excitation R_left Measured TIME[s] Measured R_left R_right i Linear Excitation R_right R_center TIMES [s]

21 WORKING PROGRESS Department of Information Engineering Redesign the mechanics of the tibial insert or change the type of transduction of the load applied to reduce the hysteresis due to the intrinsic viscoelastic properties of polyethylene. Develop an alternative method of supply the autonomous sensor, i such as systems based on the recovery of energy from mechanical vibrations.
