Hochschule Niederrhein. Your way.

Within the scope of their studies, there are many opportunities that allow our students to implement creative and technically demanding projects. We would not like to withhold these from you either. The projects presented are a colorful mix of projects ranging from student research projects or term papers to master's theses.

Development of a children's bag made of artificial leather with a light effect

 

 

The 5th semester project group of the winter semester 19/20 developed a children's backpack made of artificial leather with light effects for their client Vowalon Autovermietung GmbH. Because unfortunately many children still have road accidents. The Lumi monster backpack has numerous reflectors and built-in light effects. The project was supervised by Prof. Dr. Karin Finsterbusch.

 

Project group 6 of the 5th semester projects WS 19/20 developed the Baby Carrier 2030 in cooperation with ErgobabyTM.The baby carrier impresses with its simple, stylish and conventional design, which integrates various sensors and actuators. The baby carrier can be worn in front of the chest and on the back and is made of wind-, water- and dirt-repellent material, is breathable and robust. To protect the baby, functional LED sequins are integrated into the appealing design pattern using technical embroidery technology. In addition, the baby belt can be tempered using heated wires. The team was supervised by Prof. Dr. Anne Schwarz-Pfeiffer.

Development of functional sequins equipped with SMD components and their processing using technical embroidery

 

 

 

Functional sequins are developed in Marit Ulferts´bachelor thesis using a special cutting method. A carrier film is laminated on the surface with a full-surface copper adhesive film. The ladder structures are programmed in CAD software. With the UCT (universal cut tool) pulling knife of the cutter, the surface of the copper layer is cut according to the pre-programmed structure, so that excess copper surfaces can be easily removed by peeling off the copper foil. The functional sequins produced in this way are then fitted with the electronic SMD components and automatically fixed and contacted on the textile using technical embroidery technology.

The development of a model of a smart pullover with on the back through a wave-shaped arrangement of functional LED sequins serves as an application example.

Decorative and functional miniature beds

 

 

The 5th semester project group Team 4 “Stitch Happens” of the winter semester 19/20 developed decorative and functional miniature beds in cooperation with the company ZSK Stickmaschinen GmbH. The functional miniature beds are equipped with a heating function through embroidered heating wires using Tailored Fiber Placement (TFP), which temperature can be controlled manually. In addition, a pressure-sensitive occupancy sensor is integrated that lights up an LED when a certain pressure acts on the sensor. The project team was supervised by Prof. Dr. Anne Schwarz-Pfeiffer.

 

In our lives we are surrounded by textile surfaces - our clothes, at home on the sofa or at the table, or even when we are sitting in the car. Thus, textiles offer an ideal interface or an interface with a technical system that serves for communication.

This student project shows how we can use tablecloths, cutlery, plates and candlesticks as interaction surfaces to control light, warmth and music and hence interact with our table neighbours at the same time. The responsible lecturers were Prof. Dr. Christof Breckenfelder, Barbro Scholz and Prof. Dr. Anne Schwarz-Pfeiffer.

Interactive, textile panels

 

The textile integration level of individual components of a Smart Textiles System is constantly increasing. With help of the embroidery technology it is possible to apply LED-mounted sequins automatically to a textile structure and embroider them with electrically conductive yarns. The yarns also serve as data transmission lines and connect the sequins to a circuit board and a textile pressure sensor. The pressure-sensitive sensor causes one or more LEDs to light up depending on the applied pressure. The sensor-controlled LED matrix can be used both as a wall panel and as a control and steering surface in home textiles. The matrix is developed in cooperation with Madeira Garnfabrik Rudolf Schmidt KG.

Sound Emitting Embroidered Textiles

 

As part of the 5th semester project WS 18/19, a smart jacket with embroidered textile data conductors and various sensors and actuators was developed on the subject of Sound Emitting Embroidered Textiles in cooperation with project group 24 and the company ZSK Stickmaschinen GmbH. The jacket combines technology and nature and takes up the illustration of the jungle. Controlled by a microcontroller and the integration of textile speakers, the sound of a roaring lion is acoustically represented by closing the push buttons. The winding snake shines through the use of functional LED sequins. Prof. Dr. Anne Schwarz-Pfeiffer supervised the project team.

 

 

The coat integrated different sensors in the epaulette and actuators in the bags.

The epaulettes exist of rain sensor conductor boards which are cased with 3D printed frames. If the rain sensor measure humidity they activate lights which are integrated into the coat bags. There is also a light sensor on one of the epaulettes which is interacting with the light intensity of the surrounding.

The light bags are 3D printed flexible constructions of two-parts. They exist of an upper shell with a layer of black dimout film and an equivalent base. They function as a cover for blacklights of discarded smartphone displays and work as light elements. The design is inspired by the Audi A8 Type D4/4H.

LIGHT|WEAR Analysis and Implementation of Light Emitting Textiles with regard to the Fashion Industry

 

 

 

LIGHT|WEAR describes a limited light emitting fashion collection.

With smart designs, minimalistic cuts, strong lines and exciting patterns LIGHT|WEAR will not only increase the awareness for light emitting fashion but also deliver fully functioning pieces using a unique light emitting technology. Within the production of the light emitting fabric, high quality optical fibers are embroidered onto the fabric, using a special embroidery technique, the tailored fibre placement, that allows almost every kind of desired pattern. The optical fiber is then connected to a small wearable laser which functions as light source. Upcoming new pieces can even be controlled via app with different settings for the light emitted feature. Due to the smart construction of the LIGHT|WEAR pieces, lasers can be exchanged and thus the same clothing piece can emit different colours within the visible spectrum of light, even infrared light.

LIGHT|WEAR pieces display their full potential in barely illuminated environment. When surroundings get darker, it only takes the push of a button to defy the gloomy void of night-time.

In Lucie Brunner´s bachelor thesis, the Bauhaus is reinterpreted. The topic of color-changing textiles is worked out with a special focus on photochromic materials. By combining typical design features of the Bauhaus and using color-changing photochromic yarns, different fabric structures are produced. The developed woven samples are evaluated with regard to their color change effect and their light absorption, as the fabric construction influences the color change effect. In addition, the irradiation time and the power of the light source influence the color intensity of the photochromic yarns.

Smart glove with integrated textile bending sensor, textile data conductors and biofeedback using LED - Functional Sequin Devices

 

 

 

Using the embroidery technology, a large number of textile sensors and actuators are already being produced in medical technology and sports. In the field of therapy gloves, embroidery technology is becoming increasingly important.

Current therapy gloves for finger training actively contribute to rehabilitation only by using external power source, impulse generator or software connection and often do not integrate biofeedback for learning success control and motivation increase.

The smart glove consists of a glove with integrated bending sensor in the finger and an attachable cuff. The signals from the textile bending sensor in the glove are controlled by a microcontroller in the cuff and forwarded to the LED-Functional Sequin DevicesTM which take place at the back of the hand.

The circuit layout is made of conductive thread which is implemented by embroidery technology. The embroidered pattern contains the textile data conductors, the LEDs and the connection to the microcontroller. The LED-FSDsTM are conventional sequins with circuit layout and are carriers of small electronic components. With a defined and reproducible process, they are automatically placed, fixed and contacted.

The smart glove enables the mobile sensory detection of the motor mobility of the fingers. In addition to the finger training, the smart glove also serves as biofeedback by visualizing the motion signals using the LED-FSDsTM. The biofeedback signalizes the success of the therapy to the operator, acts as a self-control over the motor training process and increases the motivation and the learning process.
