Stretchable Microelectrode Array
Stretchable microelectrode arrays (stretchable MEAs or sMEAs) (also referred to as stretchable microelectrode array, multielectrode arrays) are a specialized type of microelectrode array (MEA) with a key advantage; they can be deformed, stretched, bent, and twisted while maintaining electrical functionality whereas standard MEAs break upon mechanical Structural load, loading. Flexible MEAs (flexMEA), which are often confounded with stretchable MEAs, lie in between stretchable MEAs and standard MEA in terms of their mechanical properties because they bend and twist to some degree, but not stretch. Just like traditional MEAs, stretchable MEAs consist of a few thousand microelectrodes that allow recording or stimulation of electrical signals from cells (neurons, muscles, etc.), and are used in vivo in a living being or in vitro with cell cultures. Theory A stretchable conductor typically consists of two components: an elastomeric insulator and an electrical conductor. There are sev ...
