Abstract

Un sensor de contacto de baja impedancia detecta el contacto manual de un substrato eléctrico realizado por un usuario humano. El sensor de contacto incluye una primera almohadilla del electrodo conductor que tiene forma geométrica continua cerrada, y un segundo electrodo conductor que rodea de manera substancial al primer electrodo en una relacion espaciada y coplanar. El primero y segundo electrodos están dispuestos sobre la misma superficie del substrato. Un elemento eléctrico activa está ubicado en el substrato, cerca del primero y segundo electrodos, y esta eléctricamente acoplado al primero y segundo electrodos.
