Implant development is teamwork
The development of implants is an interdisciplinary field of engineering, technology and preclinical clinical and industrial partners. Pioneering ideas combined with latest technology support ground breaking preclinical and clinical studies. Additional to newest technology we focus to increase device reliability and functionality, paying particular attention to ensure a high degree of usability and ease of use.
Currently we focus on:
- nerve and muscle stimulators for basic research in small animals
- implantable battery powered data acquisition systems
- 3D modeling and planning of specific electrode designs and their placement in situ prior to production and application
- intraoperative measurement of muscle strength and bioelectric signals as well data processing
- stress evaluation in various situations of daily living
