AI Technical Summary
Technical Problem
Traditional force sensors are complex to design, costly, large in size, and have poor robustness to environmental changes, making them difficult to integrate effectively into compact systems.
Method used
A pressure sensor is encapsulated within a cavity, combining a first material and a second material. The first material encloses the sensor, while the second material covers the first material and has a higher Young's modulus, used to transmit external force. The pressure sensor measures the pressure within the first material.
Benefits of technology
A compact force measurement device has been achieved, which improves measurement accuracy and sensitivity, enhances reliability and durability in harsh environments, and reduces manufacturing costs.
