Custom FSR Sensors: What to Prepare Before an Inquiry

Explain how it will be used before choosing a shape

For a custom FSR flexible pressure sensor, begin with the application, available mounting space, contact positions, loading method, routing and testing requirements. You do not need every detail at once. Dimensional sketches, assembly photographs and a description of the target action can all support an initial discussion. The outline, sensing area and delivery specifications need drawing and prototype review.

A film inside a cushion, between mattress layers or at a contact point in equipment may face different surfaces, support and mounting methods. Product photographs help explain structures, but cannot replace project-specific selection.

Application: what change do you need to detect?

State where the product will be installed and what change it needs to detect. A seat project might concern occupancy, local contact or force in separate zones. A mattress project might concern bed occupancy or contact changes in different areas. Describe the target action and the response expected from the system to support discussion of sensing positions and zone layout.

If the application is still in development, describe the target action, current structure and the questions to validate. Keep uncertain parameters as review items; do not invent an untested value just to complete an inquiry.

Mounting: provide dimensions and the surrounding materials

Beyond the outline dimensions, provide the available thickness, fixing positions, bending requirements, loaded area and the materials and support above and below the film where possible. Assembly photographs explain the contact positions; dimensional sketches help define boundaries.

For seats or mattress stacks, state the intended layer, whether soft material covers the contact surface and whether preload remains after assembly. Include these conditions in later prototype and test discussions.

Routing: consider assembly and termination together

Provide the preferred tail-exit side, available length, any harness or connector requirement and the control-board connection position. If the interface is undecided, show the relative positions of the board and sensing area before discussing feasible connections.

The film outline and tail layout need to fit the assembly. Inferring wiring from a product photograph can overlook installation constraints. Review routing and mechanical integration again during system development.

Testing: explain how the load is applied and results assessed

If you already have a target force range, trigger condition or decision logic, provide its test basis. Also describe the loading contact face, loaded position, loading and unloading methods, and whether the required observation is a trigger state or continuous change.

If testing is unfinished, list the questions you want to validate and define the conditions at the prototype stage. This article makes no universal commitment on range, accuracy or service life. Performance and decision conditions depend on project agreement and test results.

A checklist to share with your engineers

For an unreleased product, check your permission to share the information first. You can begin with a structural description that excludes customer names and confidential details, then agree how to exchange further information.

• Application and the contact or force change to detect.
• Outline dimensions, available thickness, mounting position and assembly photographs.
• Sensing area, contact method, surrounding materials and support.
• Tail direction and length, connector or controller-board interface requirements.
• Existing test methods, target decision conditions and unresolved validation questions.
• Prototype quantity, project stage and the delivery scope to discuss.

Can we start before the drawing is finalized?

Yes. Start with an application description, photographs and dimensional sketches. Baoshengda can discuss structure and sensing requirements from the available information. Suitability, customization and testing still require project review.

Explore the products and customization scope, or send initial requirements through the inquiry, telephone or WeChat options on this website. Clear use conditions help turn the discussion into a reviewable structure and prototype plan.

Project scope and source

This article supports project discussions. Specific materials, sensing range, structure and test conditions must be reviewed against your drawing and requirements.
