Thin-film circuits can be applied to flexible polyimide substrates making them capable of being bent and shaped considerably without impact on circuit performance or reliability. As such, the combination of flexible material and thin-film circuit geometries is leading medical designers to consider how far they can go in an attempt to enhance their sensors for advanced procedures, and improved patient care.
For medical designers pivoting from one scale to another, however, there is often an immediate challenge of resolving their engineering ideas using dramatically less real estate. Considering that micron-scale thin film allows for a reduction in lines and spaces by over 100%, and also allows for multilayer techniques, a certain amount of education is required for designs to be production-ready.
This Tech Brief aims to outline the top 7 considerations biosensor circuit designers should pay close attention to early in the earliest stages of prototype development.
