Editing Printed circuit board (section)

== Uses ==
Printed circuit boards have been used as an alternative to their typical use for electronic and [[biomedical engineering]] thanks to the versatility of their layers, especially the copper layer. PCB layers have been used to fabricate sensors, such as capacitive pressure sensors and accelerometers, actuators such as microvalves and microheaters, as well as platforms of sensors and actuators for [[Lab-on-a-chip]] (LoC), for example to perform [[polymerase chain reaction]] (PCR), and fuel cells, to name a few.<ref>{{Cite journal |last1=Perdigones |first1=Francisco |last2=Quero |first2=José Manuel |title=Printed Circuit Boards: The Layers' Functions for Electronic and Biomedical Engineering |journal=[[Micromachines]] |date=2022 |publisher=[[MDPI]] |volume=13 |issue=3 |page=460 |doi=10.3390/mi13030460 |pmid=35334752 |pmc=8952574 |doi-access=free }}</ref>
