buttonsens®: precise finger force measurements

measures the force on fingers during activities performed in ergonomics, manufacturing quality control, and biomechanics.

finger force measurements - mobile force measurement on hand | buttonsens - novel.de

buttonsens is attached to the finger or thumb and detects the normal force acting on the sensor. The buttonsens force sensor is the ideal solution for mobile applications in which the load on the hand is to be monitored in daily routines.

The buttonsens utilizes one fully calibrated, capacitive sensor made of textile materials which is connected to the small and lightweight loadpad electronics. It either communicates wirelessly via Bluetooth with a mobile device or can also be connected via cable to novel’s industrial pliance measuring systems.

loadapp and buttonsens

Data acquisition, real-time transmission via Bluetooth, and data evaluation is captured with the loadapp. The app displays force over time and provides immediate feedback regarding the applied force via an auditory, visual, or vibratory signal. The measured data can be stored on the smartphone and to the cloud and also transferred to a computer for detailed analysis.

The buttonsens force sensor helps the user to meet specified load limits or to achieve target values. As the sensor is thin and highly adaptable there is minimal disturbance to the proprioceptive perception.

Combining the buttonsens with loadpad palm sensors enables force measurement during grasping and other manual tasks. More information about loadglove:
