and tactile feedback.
Four hands-on simulations explain a proposed capacitive force sensing system and how it could communicate pressure through fingertip vibration. Explore the electronics, test virtual pressure, and analyze synthetic signals.

Capacitive Force Sensor
Change the plate gap and inspect the modeled capacitance, ADC reading, and PWM cue.
Open Force Sensor →Surgical Pressure Simulator
Explore a virtual instrument interaction, tissue deformation, and pressure-dependent alerts.
Try Surgical Simulator →Calibration & Signal Analyzer
Generate synthetic signals, introduce noise, tune filtering, and run two-point calibration.
Open Analyzer →About this prototype
This site demonstrates design concepts, not clinical pressure limits, realistic tissue injury predictions, or measured force accuracy. The models are simplified by design. Use the four pages to explore how the proposed system might behave.
