Bend your fingers and control your lights. Bi-directional, so it goes from -180 to 180 (larger flex angle possible). Longer versions available as BendMini and BendShort. Need another size, width, length, thickness, stiffness, ... ? Contact us with your request - we can provide you with the solution that best matches your requirements. See this videoclip for a demo of the BendShort !

Application examples

  1. Combine with the TouchGlove and create your own custom dataglove for capturing finger bending, capture hand movements with a GForce3D).
  2. Go whole-body with a bodysuit, capture all your joints' movements and express with all your extremities. A couple of BioVolt sensors will capture muscle tension. Use a GForce3D on your feet and hands to capture kicks and punches. A Hot will keep you in check of your body temp.
  3. Since it's such a thin and flexible sensor, it's usable for measuring airflow.
  4. Wireless Wi-microDig with one of our BatteryPacks recommended in all cases to operate without tether.
  5. For bookworms: has also been used to detect turning of pages.

Technical specifications

Product BendMicro sensor
Version 2.0 (May 2011)
Sensing parameter flex angle multiplied by flex radius
Sensing method Flexpoint piezo-resistive technology
Range -180 to +180 (larger flex angle possible)

Weight 15 g (0.5 oz), incl. cable
Cable 1.0 m (39 inch), shielded, red wire = power, black wire = ground, white wire = sensor output, maximum extension 30 m (98 ft)
Connector male plug with a row of 3 pins spaced 2.54 mm (0.100 inch)
Software support

  1. 09 Dec 2014: SensorX v1.00 for MacOS and Windows (64bit, contact us for the 32bit version) from source code in Max. For multiple sensors or sensor outputs, run multiple instances of the application, each started in its own folder. Use together with Connect (MacOS / Windows) or BlueMIDI (Windows).

Application notes The sensor output is determined by both the angle between the ends of the sensor as well as the flex radius; bending the sensor sharply will result in a higher value than bending the sensor smoothly, when keeping the ends in the same position. Longer versions available as BendMini and BendShort.
