The clinical application of neural implants is often hindered by a lack of long-term stability. Therefore, we focus on the safe and efficient use of neural implants within the human body to improve the quality of life for patients, providing them with greater autonomy and well-being. In this effort, we develop essential quality criteria to enable standardized evaluation in this field. The evaluation follows a defined procedure, providing a decision-making foundation for further technological steps at an early stage of development.
