Patented technology that reduces FSR drift by 80% — making force sensors practical for scales, smart shelves, and sustained-load applications.
Emerging "smart shelf" technologies simplify inventory management, help detect theft, and improve customer experience. Force Sensing Resistors are often considered for these applications because of their low cost, high dynamic range, and ability to precisely identify product footprints — but drift can pose a significant challenge.
All Force Sensing Resistors drift, or become more conductive over time, under a fixed load. The conductance of some FSRs will increase by more than 30% in 48 hours. Such high rates of drift complicate the use of FSRs in scale-type applications.
Sensitronics' patented LowDrift FSR technology reduces drift to levels that are easily managed, or in some cases ignored entirely.
Under constant pressure at 2 PSI over 48 hours, Standard FSR inks drift almost 12%. The LowDrift FSR ink drifts only about 2.5% — representing an 80% reduction in drift.
LowDrift FSR technology is ideal for smart shelves, scales, inventory management systems, medical devices requiring sustained pressure monitoring, and any application where a sensor must provide stable readings under constant load.
