Force torque sensing is the sense of touch for robots — without it, robots cannot do precision assembly peg in hole , safe human collaboration, or delicate grasping. It is a universal requirement across every robot form factor

Force-torque sensors and tactile sensing: technology and investment research
403 words · Vault research updated Jul 12, 2026
Technical bottleneck
- Bottleneck type: Manufacturing precision / Calibration
- Technical constraint: Silicon strain gauge linearity, hysteresis, and temperature drift require laser trimming and thermal compensation; cross-axis coupling (e.g., Fx producing a false Fz reading) must be <1% through mechanical isolation; tactile sensor spatial resolution (<1mm) and durability (>1M cycles) trade-off
- Economic constraint: ATI Industrial Automation (Novanta) dominates F/T sensors with 60%+ share; custom integration into cobot and humanoid joints is complex; calibration and compensation electronics add unit cost
Adoption
- Driver: Humanoid robot development programs (every hand needs tactile sensors); surgical robot F/T feedback for haptic control; cobot safety standards requiring force monitoring; DoD manipulation programs
- Blocker: Robot designs using current sensing in motor windings as proxy for force (imprecise but cheaper); capacitive tactile sensors displacing strain gauges; Chinese F/T sensor quality improvement
Public companies exposed
NOVT (Novanta/ATI Industrial Automation)
TDY (Sensor Technology)
VPG (Vishay Precision Group — strain gauges)
SYNCM (Synaptics — capacitive touch)
Validation signals
ATI/Novanta F/T sensor revenue growth >20%; tactile sensor design wins on humanoid hand platforms; medical device F/T for surgical robotics
Invalidation signals
Motor-current-based force estimation achieving <1N accuracy; commoditization of F/T sensors from Chinese manufacturers; humanoid programs reducing finger count and simplifying end-effectors
