Tissue-sensor interface inflammation

“Tissue-sensor interface inflammation” describes the cascade of immune and fibroproliferative processes triggered by the implantation of bioelectronic or biosensor devices in living tissue. The foreign body response is characterized by recruitment of immune cells (macrophages, neutrophils, microglia in neural tissue), production of inflammatory cytokines, local vascular changes, and eventual formation of fibrotic capsules that isolate the implant. This response impairs device performance, potentially leading to decreased signal quality, device displacement, or failure. Recent bioengineering strategies include anti-inflammatory drug delivery, biomaterial surface modification, and modulation of immune cell responses to mitigate inflammation and prolong sensor functionality[1][2][3][4][5][6].
