II. Working Principle

Based on the piezoresistive effect: When the silicon-based sensitive element is deformed by an external force, its resistance value changes linearly with the force.

Built-in ASIC chip: Factory calibration has been completed for offset, sensitivity, temperature drift, and non-linearity, no need for external circuit compensation.

Force is transmitted to the sensing core through the stainless steel ball, and a digital signal proportional to the pressure is output (I2C), with strong anti-interference and easy integration.

III. Typical Applications (Scenario-based)

1. Medical Equipment (High Precision + High Reliability)

Infusion pump / injection pump: Pressure feedback, pipe blockage detection, ensuring infusion accuracy and safety.

Dialysis machine: Fluid pressure monitoring, pipeline blockage warning.

Portable medical equipment: Miniature force control interaction (such as surgical instrument force feedback).

2. Industrial Automation and Robotics

Robot end effector: Precise control of grasping force (anti-drop / crushing prevention), assembly force monitoring.

Key / switch replacement: Touch sensation detection, force degree recognition (such as control panel, household appliance buttons).

Thin and light material detection: Film / paper tension, adhesion pressure measurement.

3. Consumer Electronics and Intelligent Interaction

Pressure-sensitive keys for smart devices: Force-level response (such as game controllers, touch pens).

Wearable devices: Contact force monitoring, posture recognition.

4. Testing and Measurement

Micro-pressure / force value calibration: Laboratory precision force reference, product feel testing.
