Smart Garments are the Future of Wearable Industry
Sensor is a device, module which is capable of measuring or detecting signals, changes in its fixed environment and sends the obtained information to other electronics, mostly a computer processor. Body’s vital signs and important working measurements are identified through electronic sensors. The researchers developed a garment sensor that is placed in the wearable garment and then it works accordingly. Temperature of the body, respiration system and heart rate could be monitored using garment sensors. The sensor-embedded garments are washable that stay close to the body of the wearer. People being ill, either at home or in the hospital can be taken care of. The activity of athletes and astronauts health is monitored using these garment sensors. Thin-paper like sensors are designed that measures vital signs of the body but needed to be inserted or placed inside the body that is a delicate process. Japan is developing new types of fabric fused with technology. Smart clothing has the ability to enhance user to experience virtual reality games. With the 2020 Tokyo Olympics, the researchers had planned in production of high-tech attire to professional athletes.
GARMENT SENSOR DESIGN
· A shirt with 30 temperature sensor was designed and an accelerometer that can measure the wearer’s movement, heart rate and breathing rate is measured.
· The measured data is transmitted wirelessly to a smartphone.
· The electronic sensors consist of long, flexible strips that are encased in epoxy.
· It is woven into narrow channels in the fabric
· The channels in the sensor are provided with small openings that allow the sensors to be exposed to the skin.
Polyester blend was the fabric chosen for the property of moisture-wicking and its ability to conform to the skin, similar kind of shirts worn during exercise. The sensor is provided with the property of shifting to other garments in need and also with washable property. It visualizes as a T-shirt, but from inside, it can work like an electronic part that touches your skin.
Prototype shirts are tested when wearied in gym and different body signs are measured and calculated in mobile phones. The development started when other types of garments like pants were developed. That is used in measuring or monitoring blood oxygen levels and other indicators of health.
They are extensively used in smart textiles. They are thermal responsive polymers, light-responsive polymers, piezo-responsive polymers, moisture polymers, pH-responsive polymers, moisture-responsive polymers.
