They are flexible pressure-sensing materials made by weaving conductive yarns into fabric in an array structure. Every warp-and-weft intersection forms an independent sensing unit; when pressure is applied, the unit’s electrical signal changes. The system converts this into a pressure value for each point and aggregates it into a real-time pressure distribution heatmap. E·SEN·FAB focuses on a pure textile-based approach, so the fabric looks and feels close to ordinary textile.

Frequently Asked Questions
Find quick answers to the most common questions about our products, technology and services.
What are textile pressure sensors?
How do textile pressure sensors differ from film or rigid sensors?
The key differences are the base material and how the sensor conforms to surfaces. Film sensors use polymer films as the carrier and are prone to delamination and signal drift after long-term bending; rigid sensors are hard and bulky, making it difficult to fit curved surfaces and the human body. Electronic textiles are woven integrally from yarn, offering better flexibility, breathability and conformance — they bend freely along mattresses, cushions, garments and robot surfaces. The integrated structure suppresses interlayer slippage, keeping output more stable under repeated pressure.
What data can textile pressure sensors collect?
A single sensing point records local pressure changes, while an array of multiple points records pressure positions and the overall pressure distribution. It can also compare force changes across different movements or moments in time.
How do I choose the number of sensing points, point spacing, measurement range, accuracy and sampling rate?
Sensing point density, range, accuracy and sampling frequency vary by product, and all support customization for specific application scenarios. For exact values, refer to the official datasheet of the corresponding product. If you need a specific point spacing or sampling frequency, contact our technical team for an evaluation.
Are the sensors washable?
Pure textile-based flexible pressure sensors are designed to be washable, making them easy to clean and maintain in body-contact scenarios such as mattresses, cushions and wearables.
Can the sensors bend, fold or stretch? How is service life determined?
Fabric-based sensors accommodate a range of bending; the stretch range of stretchable models is defined in the product specifications. For projects involving repeated bending, folded storage or long-term compression, test conditions can be defined based on bending radius, load and frequency of use. Specific limits and durability depend on the model’s user manual or test results.
What pressure sensing products and solutions does E·SEN·FAB offer?
E·SEN·FAB provides textile-based flexible pressure sensing and integration solutions, covering sensing textiles, signal acquisition hardware and visualization software. Representative products and solutions include pressure-sensing mattresses and cushions, plantar and gait analysis devices, smart tactile gloves, robot electronic skin, and smart-cabin pressure sensing solutions.
How do pressure-sensing mattresses help in pressure injury (pressure ulcer) care?
The E·SEN·FAB pressure-distribution electronic textile mattress records the pressure distribution between the body and the bed surface as well as how long each area stays under continuous pressure, and alerts caregivers when configured conditions are met. It supports daily pressure observation in hospitals, rehabilitation facilities, eldercare institutions and home care. Certain configurations can also show in-bed / out-of-bed status and pressure distribution in different lying postures.
How are pressure alerts triggered? Can thresholds be adjusted?
Alert thresholds can be set based on pressure level and duration. Once the configured conditions are met, the system raises alerts through the software interface or audible/visual signals according to the configuration. Specific settings follow the software documentation and project plan.
Will the sensing layer affect the feel of the mattress?
The sensing layer is a flexible textile that can be integrated into the mattress structure. Sleep feel depends on the mattress’s own firmness, fabric, sensing layer thickness and installation position. For configuration and bedding compatibility details, refer to the product documentation.
What data can the smart pressure cushion monitor?
The cushion observes the pressure distribution between the hips/legs and the seat surface, shifts of the center of pressure, and seated duration. Recognition and alerts for states such as leaning or crossing legs depend on the specific model and software configuration.
How does the sedentary (prolonged sitting) reminder work?
Models with a sedentary reminder can record continuous sitting time according to the configuration and issue a reminder once the set duration is reached. Timing rules, reminder methods and threshold settings follow the product documentation.
