Sensing resistor membrane sensor switches for medical electrode pads
A Force Sensing Resistor (FSR) is a variable resistor in which resistance decreases when pressure is applied.
In simple terms, the device is made of a circuitry layer, printed with a conductive ink (typically silver) and a force sensing layer, printed with a pressure sensitive ink.
The two layers are separated by a spacer.
The key ingredient is the pressure sensitive ink, which is customized to meet the application requirements.
Force sensing can be used as a simple potentiometer or a pressure sensor. It can be incorporated in a touchpad or a force measuring device.
More complex applications include medical, musical instruments and automotive seat detector.
Central Midori has been manufacturing force sensors for more than 6 years.
