[أجهزة MEMS] تحليل مبدأ العمل لأجهزة استشعار غاز أشباه الموصلات
Semiconductor gas sensors are MEMS devices: metal-oxide layers change conductivity when gas reacts at elevated temps, read by resistor or FET circuits. Design hinges on material choice, micro-heater control, packaging and signal conditioning to balance sensitivity, selectivity and stability for real-world monitoring.
