This sensor has been replaced by the BendMini v1.1.
Bend your fingers and control your lights. Goes from 0° to 180°
(larger flex angle possible). Shorther version available as
BendMicro,
longer version as
BendShort.
See this videoclip
for a demo of the BendShort !
Application examples
- Combine with the TouchGlove and
create your own custom dataglove for capturing finger bending, capture hand movements with a
GForce2D&Tilt2D.
- Go whole-body with a bodysuit, capture all your joints' movements and express with all your extremities. A couple of
Curls
will capture muscle tension. Use a
GForce2D&Tilt2D on your feet and hands
to capture kicks and punches. A Hot will keep
you in check of your body temp.
- Since it's such a thin and flexible sensor, it's usable for measuring airflow.
- Wireless Wi-miniDig
with BatteryPack
recommended in all cases to operate without tether.
- For bookworms: has also been used to detect turning of pages.
Technical specifications
| Product |
BendMini sensor |
| Version |
1.0 (15 December 2000) |
| Sensing parameter |
flex angle multiplied by flex radius |
| Sensing method |
piezo-resistive |
| Range |
0° to 180° (larger flex angle possible) |
| Minimum flex radius |
5 mm (0.2 inch) |
| Output impedance |
6 KOhm (at 0° flex angle) to 500 KOhm (at 180° flex angle), in parallel with 47 KOhm |
| Calibration (using minimum flex radius) |
| Degrees |
Voltage (use 5 V power supply) |
7-bit MIDI value (use 'no processing' editor preset) |
| 0 |
4.33 |
110 |
| 180 |
0.00 |
0 |
| Power supply |
1.0 to 10 V DC, 0.1 mA at 5 V |
| Sensor dimensions |
63 x 7 x 0.1 mm (2.5 x 0.3 x 0.004 inch) |
| Weight |
15 g (0.5 oz), incl. cable |
| Cable |
0.90 m (35 inch) twisted, unshielded, 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) |
| 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. Shorther version
available as BendMicro,
longer version as BendShort. |
