As syseng68k suggests, probably that simple strain gauge tranducers would do the job (on the mechanical link between the actuator and the control surface, and even on the control surface itself). All the strain signals (along with IMU signals, GPS signals, AoA signals, airspeed signals,...) could feed in real time an aerodymical model of the A/C (control surface+airframe) to derive these aerodynamical authorities and much more: in particular, it could also help to cross-check the integrity of all the incoming signals (navigation and attitude, AoA and airspeeds,...) in a more efficient/flexible way than it is currently done, and generate a reliable stall warning.
