Position Sensors

The FlexiPot™ Strip and Ring tactile potentiometers and/or position sensors are used to identify location or position and adjust output. These sensors can measure position between any two surfaces. These ultra-thin, flexible sensors are ideal for consumer electronics, industrial control, and medical device applications. The low power requirements combined with linear output makes these position sensors ideal from both a manufacturing and user perspective. The sensors are customizable and available off-the-shelf in ring and strip formations.

The best user interface, whether in consumer electronics or industrial controls, contains sensors that cause minimal interference, meaning the user may not even know they are there. FlexiPot, by Tekscan, is a flexible membrane potentiometer with an ultra-thin (0.008"), lightweight profile.

FlexiPot™ Position Sensing Applications

Position Sensor on MP3 Player

FlexiPot membrane potentiometers are ideal for integration into:

  • Consumer electronics (user interface in PDA)
  • Electronic Menu Navigation (scroll through options)
  • Industrial Controls
  • Medical Devices (plunger position)

Benefits of FlexiPot:

  • Low-power
  • Flexible
  • Ultra-thin (0.008")
  • Linear Output, low error (±2%)
  • Customizable
  • High-Temperature Option (up to 400ºF)

Featured Video: How FlexiPot Works

When a contact is applied to the sensitive surface, an electrical contact occurs between the top and bottom layer of the sensor, creating a variable voltage divider. This video demonstrates the linear and rotary potentiometers reacting to user input to provide positional data.
