Precise finger force measurements
Measure force at the finger-object interface.
Compact textile sensors for quantifying thumb and finger force during button operation, work tasks and biomechanical interaction.
What is buttonsens?
Finger force measurement for interfaces and actions.
Using a textile sensor, buttonsens measures force when pushing a button or when a finger interfaces with an object. In ergonomics, manufacturing quality control and biomechanics, it quantifies the force applied by the finger during real actions.
The sensor is attached to the finger or thumb and measures the normal force. It uses one fully calibrated capacitive sensor made of textile materials and connects to small, lightweight loadpad electronics.

Real-time analysis
Measure, store and review force curves.
A detailed analysis can be performed on the data collected by the app by storing it on the device and transferring it to a computer. The mobile app displays force over time and allows threshold-based audio or visual feedback.
Measurement workflow
Turn a button press or touch action into measurable data.
buttonsens is suited to tasks where a small contact surface determines usability, safety or repeatability. The textile sensor is attached to the thumb or finger, the user performs the normal action, and the system records the force needed to trigger, hold or repeat the interaction.
This is valuable for comparing switch designs, documenting ergonomic load, training operators and identifying excessive force during repetitive work. The same principle can support biomechanical studies where fingertip loading must be quantified without a rigid handle or fixed laboratory setup.
Typical outputs
Activation force, peak press force, hold force, press duration, repetition consistency and threshold compliance.
Useful comparisons
Compare button geometry, tactile feedback, glove conditions, user groups, assembly steps or product prototypes with consistent force metrics.
