This work describes the design, fabrication and laser trimming aspects of a low-cost compressive force sensor with analogue signal conditioning, designed for a medical syringe pump. First, the general design aspects are discussed, in view of facile and reliable batch production and measurement performance. Then, the circuit's trimming procedure is presented, featuring single- pass adjustment of sensor output in its final state, i.e. with all components mounted, without prior passive resistor trimming. Key words: thick-film technology, force sensors, manufacturing, trimming
