The relationship between surface wear and contact resistance during the fretting of in-vivo electrical contacts

Significance of output:

There is increasing interest in the application of embedded electronics within the human body. There are many technological ideas but no published research on the conduction surfaces which allow the implementation. The paper presents research on intermittency phenomena in electronic devices as a result of fretting caused by body motion on the connector surfaces. The work shows that the surface films on the permitted metals cause the intermittency phenomena and that intermittency events occur in every fretting cycle. The research links the level and number of events to the wear process. This is critical to future application of in-vivo electronics.
