SOFTPOT
The SoftPot works in multiple configurations, such as linear, serpentine, and elliptical. It operates in temperatures ranging from -45°C to 50°C and is ideal for products that need a sealed sensor with a tight form factor. It’s no wonder it became a popular option for clients in the medical, dental, and robotics industry. The SofPot is also a versatile sensor that can operate by human touch. It can provide the desired linear output regardless of the shape of the product it’s attached to.
How it Works?
In simple terms, the SoftPot membrane potentiometer is a resistive element, which comprises a conductive resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a voltage divider.
The SoftPot is a three-wire system with two resistive output channels and an electrical collector channel.
By pressing a wiper down onto the top circuit the SoftPot produces the desired electrical output.
The “wiper” is a non-conductive mechanism that depresses the top circuit actuating the potentiometer from the outside of the element. The top and bottom circuits are separated by 0.15mm (0.006″) of spacer adhesive build-up and contact between the circuit occurs by pressure (usually 1-3 Newtons) from the wiper on the top circuit, pushing down until the top circuit connects with the bottom circuit to create a potentiometric output.
The construction of the wiper design can adapt to any application because most materials can serve as the wiper: plastics, metals, sliders, rollers, wheels, etc. Also, the SoftPot can also be manually (hand) actuated.

What is the SoftPot™?
At its core, the SoftPot™ is a linear membrane potentiometer — a flexible, thin resistive sensor that functions as an analog voltage divider. The sensor is composed of:
-
A sealed resistive strip
-
A non-conductive actuator (“wiper”)
-
A durable laminated structure with an ultra-slim adhesive spacer (0.15mm)
How it works: When the wiper presses down on the sensor surface, the top conductive layer makes contact with the bottom layer, producing a continuous analog signal proportional to the position of the press. The system consists of three wires: two at each end of the resistor, and one collector connected to the wiper.
Versatility in Design
The SoftPot™ excels in applications where space is limited or where flexibility in shape is required. It can be mounted on curved, angled, or irregular surfaces, making it ideal for:
-
Medical and dental tools
-
Human-machine interfaces
-
Robotic arms and motion control
-
Wearable devices
-
Industrial machinery
It can be activated using a wide range of materials: plastic, metal, rubber, wheels, sliders, rollers, and even the human finger — making it perfect for both automated and manual input systems.
