Abstract

Un sensor para el asiento de un vehículo de motor incluye una capa compresible preferiblemente de espuma dispuesta entre dos láminas conductoras. En una realizacion, la capacitancia entre las láminas conductoras se mide para determinar que objeto y si un objeto está dispuesto en el sensor, mientras en otra aplicacion, se forman agujeros a través de la capa compresible para que las láminas conductoras puedan contactar entre sí a través de los agujeros. Se describen realizaciones que tiene resistividad relativamente baja para producir un corto circuito, y una realizacion que tiene mayor resistividad en la que la magnitud del cambio y la resistencia se pueden utilizar para determinar la naturaleza de un objeto.
