Honeywell FMA Series MicroForce Sensors use piezoresistive technology to measure force across a specified range and temperature span. These sensors provide a digital output and are fully calibrated and temperature compensated for sensitivity, offset, and nonlinearity. The FMA sensors feature a stable stainless steel sphere interface for consistent performance in force measurement applications. Available in compact form, the FMA Series is compatible with SPI or I2C communication protocols.

These are the sensors you're looking for.... Well, I haven't mastered the force yet, but I don't think I even need to play any mind tricks anyway, because these really are the force sensors you're looking for, especially for medical and industrial applications. Honeywell's MicroForce FMA series are piezoresistive-based force sensors in a tiny surface mount package.
The sensors are offered with full-scale force spans of 5, 15, or 25 newtons and they are fully calibrated and temperature compensated for all errors, providing a ±2% full scale span accuracy. The sensor has a stainless sphere that can easily interface with tubing, membranes, or plungers and delivers enhanced repeatability. The FMA series outputs readings with 12-bit resolution and can easily interface to a host controller with a SPI- or I2C compatible digital output, with multiple I2C addresses available to place multiple sensors on the same bus.
