Flexible sensor detection service

Flexible Sensor Detection Service for Global Wearable and IoT Electronics

As an ISO/IEC 17025 accredited laboratory, we deliver a specialized flexible sensor detection service that verifies electrical performance, mechanical flexibility, environmental durability, and long-term reliability of bendable, stretchable, and conformable sensing devices. Our flexible sensor detection service supports manufacturers and exporters of flexible pressure sensors, strain sensors, temperature sensors, and biosensors who must demonstrate conformity to IEC, ISO, ASTM, and regional electronics standards across the European Union, North America, East Asia, and the Middle East. Every test is performed under our CNAS-accredited quality system, producing reports accepted by notified bodies, wearable device OEMs, and procurement teams worldwide.

Electrical Performance and Sensing Characterization in Our Flexible Sensor Detection Service

Sensitivity and full-scale output characterization per customer and internal validated protocols — the flexible sensor is subjected to a calibrated range of the target measurand, such as pressure, strain, or temperature, and the electrical output is recorded to determine the sensitivity, full-scale span, and signal-to-noise ratio, verifying the sensor meets the specified performance for its intended application.
Linearity, hysteresis, and repeatability measurement per IEC 60770 and related standards — the sensor is cycled through increasing and decreasing measurand values multiple times, and the deviation from the ideal straight-line response, the hysteresis error, and the repeatability are calculated to quantify the accuracy and consistency of the flexible sensor.
Response time and recovery time determination — a step change in the measurand is applied and the time for the sensor output to reach 90% of the final value is recorded, verifying the dynamic response of the flexible sensor for real-time monitoring applications.
Drift and long-term stability under constant measurand — the sensor is held at a fixed measurand value for an extended period and the output change is monitored to quantify the baseline drift and the long-term stability of the flexible sensing element.
Cross-sensitivity and interference rejection evaluation — the sensor is exposed to non-target stimuli such as temperature changes, humidity, or mechanical vibration while the output is monitored, verifying the flexible sensor maintains its accuracy in the presence of environmental interference.

Mechanical Flexibility and Bending Durability Testing for Flexible Sensors

Bending radius and cyclic bending endurance per IEC 62715-6-2 and customer protocols — the flexible sensor is repeatedly bent around a defined radius using a motorized bending test rig, and the electrical performance is monitored in situ over thousands of cycles to determine the number of bends the sensor withstands before failure or performance drift exceeds the specified limit.
Tensile strain and stretchability testing for stretchable sensors — the sensor is stretched to defined strain levels while the electrical output is recorded, measuring the gauge factor and the maximum strain before electrical failure, critical for strain sensors and stretchable interconnects.
Twisting and torsion durability testing — the flexible sensor is twisted to specified angles and subjected to repeated torsion cycles to verify it maintains electrical continuity and sensing performance under multi-axis mechanical deformation.
Folding and crease resistance per IEC 62715-6-2 — the sensor is folded along defined crease lines and the change in electrical properties and visual condition is assessed, simulating the mechanical stress of compact storage and flexible device integration.
Adhesion and delamination resistance of sensing layers per ASTM D3359 and ISO 2409 — the bond between the sensing material and the flexible substrate is tested by cross-cut tape test and peel measurement to ensure the sensor structure does not delaminate during flexing, stretching, or environmental exposure.

Environmental and Reliability Testing in Our Flexible Sensor Detection Service

Temperature cycling and thermal shock per IEC 60068-2-14 — the flexible sensor is cycled between the minimum and maximum rated temperatures for hundreds of cycles, and the electrical performance, adhesion, and visual condition are evaluated to verify the sensor withstands thermal expansion stresses and temperature extremes.
Damp heat and humidity exposure per IEC 60068-2-78 — the sensor is stored at 85 °C and 85% relative humidity for extended periods, and the insulation resistance, sensitivity, and baseline drift are remeasured to detect moisture-induced degradation of the sensing material and substrate.
UV and xenon-arc accelerated weathering per ASTM G155 and ISO 4892-2 — the flexible sensor is exposed to simulated sunlight and moisture cycles to evaluate any yellowing, embrittlement, or loss of sensing performance after prolonged outdoor or window-adjacent exposure.
Water immersion and sweat resistance testing per ASTM D870 and customer protocols — for flexible sensors used in wearable and skin-contact applications, the sensor is immersed in water or artificial sweat and the electrical performance and adhesion are retested to verify reliable operation in wet and perspiration-exposed conditions.
Washability and cleaning resistance for textile-integrated sensors — the flexible sensor integrated into fabric is subjected to multiple domestic washing and drying cycles, and the electrical performance is verified after each cycle to confirm the sensor survives the recommended care regimen.

Material and Chemical Safety Compliance for Flexible Sensors

RoHS compliance per IEC 62321 and EU Directive 2011/65/EU — quantitative screening for lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs in the sensing materials, conductive inks, substrates, and any adhesive layers to ensure the flexible sensor meets substance restrictions for the destination market.
REACH Annex XVII and SVHC screening — targeted analysis of Substances of Very High Concern including specific phthalate plasticizers, organotin stabilizers, and restricted solvents used in the flexible substrate and printed sensing layers.
Biocompatibility and skin irritation testing for wearable sensors per ISO 10993-5 and ISO 10993-10 — for flexible sensors intended for direct skin contact, cytotoxicity and skin irritation tests are performed to verify the materials are safe for prolonged wear on the human body.
Heavy metals in packaging per EU Directive 94/62/EC — verification that the sum concentration of lead, cadmium, mercury, and hexavalent chromium in the protective packaging and labels is below the 100 ppm regulatory limit.
