Smart Flexible Thin Film Pressure Sensor DF9-40 Series
Description
DF9-40 series flexible thin film pressure sensor is a new type of sensor with independent intellectual property rights of flexible pressure sensor technology. It is printed on flexible thin material with strong adhesion, bending resistance and high sensitivity of flexible Nano functional materials, so as to achieve high sensitivity of pressure detection.
The thin film pressure sensor is a resistive sensor. The output resistance decreases as the pressure on the sensor surface increases. The pressure can be measured through a specific pressure-resistance relationship. It is suitable for pressure measurement scenarios on flexible surfaces, and can be widely used in smart home, consumer electronics, automotive electronics, medical equipment, industrial control, smart robots and other fields.
The DF9-40 series currently has 500g, 2kg, 5kg, 10kg, 20kg and other different range models.
