Statt einer gebogenen Leiterplatte mit zwei Teilen können allgemein auch zwei Leiterplatten verwendet werden, die an ihren Rändern miteinander zum Beispiel durch Kleber verbunden sind. Dies erschwert jedoch die elektrischen Verbindungen. Die Anzahl der Sensorelemente und Schaltungselemente ist allgemein beliebig.Instead of A curved printed circuit board with two parts can generally also two printed circuit boards used on their edges are connected to each other for example by adhesive. This makes it difficult however, the electrical connections. The number of sensor elements and circuit elements is generally arbitrary.
