Frequently Asked Questions (FAQ)
Key engineering and procurement inquiries on force sensing technology, customization, and signal conditioning.
Ask an engineer →How do FSR sensors compare to standard micro-switches or load cells?
FSRs offer ultra-thin profiles (<0.3mm), zero mechanical moving parts, and continuous dynamic force measurement from 10g to 50kg+, whereas micro-switches only provide binary on/off states and load cells are bulky and rigid.
What signal conditioning circuit is recommended for single-point FSRs?
For simple microcontroller ADC triggers, a voltage divider with a calibrated pull-down resistor is recommended. For high-linearity analog measurements, an active transimpedance Op-Amp circuit (such as LM324 or MCP6004) is ideal.
Can custom sensor geometries, pinouts, and force ranges be manufactured?
Yes. FSRTEK provides bespoke geometries, annular rings, custom FPC tail lengths, high-temperature formulations (-40°C to +85°C), and female pin headers with rapid 120-hour prototype turnaround.
How do you eliminate crosstalk and ghosting in MATRIX tactile arrays?
Our MATRIX arrays utilize zero-potential virtual ground scanning circuits and high-speed multiplexer firmware to isolate each taxel and eliminate parallel current leakage across 256 to 3,600 sensing nodes.
What is the standard sample policy and production lead time?
Standard evaluation samples are dispatched within 24–48 business hours. Custom rapid prototypes are completed within 120 hours, followed by ISO 9001 certified volume production.
