Characteristics of the stretch sensors
Highly elastic allowing for strain or stretch of up to 80%.
Coated in a thin layer of silicone rubber.
Provides accurate measurements of biomechanics – motion sensing, posture, muscle volume and respiration.
Soft, comfortable and easy to integrate.
Washable depending on characteristics of garment/application.
Applications of the sensor
Stretch sensors are extremely versatile. They can be used in wearable applications for sport and fitness, medical, gaming and lifestyle to detect motion, volume, posture and gait.
At each end of the sensor there is a layer of non-woven textile to be used for attaching the sensor to a textile or thin substrate. This can be done by sewing (recommended by hand), taping or stamping. The stretchable zone of these samples cannot easily be attached and must be free to slide in your application. Ohmatex has developed various methods for encapsulating the sensors into fabric, depending on the garment and required position of the sensors. Based on a versatile technology these sensors can be customised to be almost any shape and size and finished in a wide variety of ways to facilitate integration.
Wireless sensor control
The sensors can be connected to most standard capacitive measuring devices or a “plug and play” unit available directly from LEAP Technology which enables the display and logging of measurements from the stretch sensors .
