Whats Next . . .
OLD DIRECTION After talking to Dr Goodall and Dr Mileva I discovered that the sensors built into a base layer will not work and I have to refine my current idea to fit within the constraints of the new information.
45
NEW DIRECTION After thinking about a new direction I decided to replace the base layer with a device that fits into the ear with a micro sensor to measure core temperature and heart rate.
46
MIND MAPPING The mind map was to determine the features of the product and to help conclude ideas of which technology to use.

FUNDAMENTAL COMPONENTS
50
HYPOTHERMIA The main way in which the device would work would be through reading the body temperature to detect early signs of hypothermia. I will look into hypothermia and its effects on the body.
When the body drops below 35 degrees the emergency system will be activated. The device will send a digital message to the lighting system inside the jacket along with a emergency distress signal.
51
52
TYMPATIC TEMPERATURE Tympatic temperature is measured from the membrane inside the ear. It measures the core temperature of a persons body.
I will use this method to detect the core temperature and heat rate.
53
AURAL THERMOMETERS The aim of looking into aural thermometers is to find out how they work.
Aural thermometers use infrared rays to detect a change. The technology is small and could be made wireless.
It re-enforces my idea of using core temperature to analyse a persons condition.
54
RESISTANCE TEMPERATURE SENSOR The PT100 Resistance temperature is able to detect temperatures from -30 degrees C up to 300 degrees C and is only 2mm in size.
The aim is to research technology that is already out on the market and test the outcome.
This technology would be perfect for my concept. The RTD is accurate up to +0.01 degree. The sensor is only 2mm in size.
55
OPTICAL SENSOR An optoelectric sensor is able to measure the heart rate by sending light through the skin which then reflects back into a photodiode which then translates the readings.
The aim is to test to see if this technology would work within the constraints of my concept.
The technology has the capacity to be shrunk down and placed into the earpiece. This perfect to read the heatbeat inside the ear.
56
HEADSET COMMUNICATION
to be able to communicate with a search and rescue team or other members of your party.
The communication can utilise bluetooth and be small enough to fit into the in-ear device. it could also be voice activated.
57
58
ARDUINO TESTS The aim of the arduino was to test the temperature and optical sensor to see how they work and get the results.
The results from the temperature sensor were not accurate so a analog digital controller to increase the voltage to get more accurate reading. The makeshift optical sensor worked great, displaying good readings of the heart beat.

TOMMY DYKES
NORTHUMBRIA UNIVERSITY
61
I met with Tommy to discuss and get help testing the PT100 temperature sensor and get general advice on electronics and the components I would like to use.
He advised me how everything worked with the sensor and arduino. He also advised on how they electronics and lighting would be powered.
As he confirmed all of my ideas for I feel confident to take the concept further and start developing prototypes.
62
63
BRAND ANALYSIS
64
CONSINUSS ONE The aim is to research a brand that already utilises the technology I am looking at and is also out on the market and conduct an analyse.
The Consinuss One device measures heart rate through an optical sensor and the body temperature using a resistance temperature detector. It comes at a cost of ÂŁ85. This technology would be perfect for my concept. The RTD is accurate up to +0.01 degree. The sensor is only 2mm in size.
65
66
KOLON SPORT LIFE TECH JACKET The aim is to research a brand that already utilises the fabric technology I am looking at and is also out on the market and conduct an analyse.
The Kolon sport jacket incorporates a wind turbine to power utilities, a built in first aid kit and has a heat system. There is 3 layers to the coat to provide maximum insulation. The jacket retails at around ÂŁ1,500.
I feel the jacket is overloaded with technology that could cause a problem. I am more interested in the fabric used to protect the person.

EXPERIMENTAL CLOTHING CONSTRUCTION
70
JACKET DECONSTRUCTION The aim of deconstructing an existing jacket was to see how all the parts were stitched together.
After I took the jacket apart I realised that the stitching looked complicated and would be hard to execute with learning how to do it.
71
72
PAPER PATTERN BLOCK I made paper templates of the separate parts. These templates are called patterns or blocks. It was a good experience to see the components of the jacket in rough form and assembling it helped me understand how the jacket was constructed.
73
74
CALICO PATTERN BLOCK Once the paper blocks are measured, they can they be pinned to calico and cut out. Once pinned they can be sewn. I discovered how hard it is even to just pin fabric together. I also learnt how to alter any part that I did not like.
75
76
STRAP TEST I wanted to investigate where the straps on a backpack are in order to work out where friction would effect the jacket.
The straps produce the most friction around the shoulders, hips and lumbar region.
I would like to create hard wearing areas on the jacket to give it a longer life span.
77
78
SEWING INDUCTION The aim of the sewing induction was to be shown how to use the machines in order to use them alone.
Now that I know how to use the sewing machines I can start to make prototypes of the jacket.
79
80
MATERIAL SAMPLES The aim of getting material samples is to determine which fabric id like to use for the jacket and the lining.
There are many to choose from and I learnt that there is many water and windproof fabric.
After looking at the fabric samples I feel I have not found the right material for the jacket. I will keep looking.
81
82
83
LIGHTING
84
FIBRE OPTIC FABRIC I ordered the fibre optic fabric in the hopes of applying it to the jacket as the lighting system.
I found that the light shinning through was not consistent as you only see the light where it reflects on the outer cable. I also found that the light is not bright enough.
85
86
PHOTOLUMINESCENCE LIGHTS I wanted to look into other possible sources of light that could be incorporated in the jacket.
Both the photoluminescence wire and strip proved to be bright and would work with my idea. I would use these types of lights within my concept. They can also go brighter with a higher voltage.
87
88
LIGHTING PLACEMENT TEST To see where the lights would be best situated and easily seen. The lights would be best utilised if the covered the biggest area and could be seen at 360 degrees.
89

91
INITIAL CONCEPT SKETCHING
92
The aim of sketching different ideas is to gain a better idea of the final form and how it should look. Creating many iterations to get the specifications required.
I realised that the best styles are the ones with block and bold areas of light which can be seen from all angles.

VALIDATION
96
ALEX PEARCE
SEYMOUR POWELL
97
I got in contact with Alex to help with my project and to validate my ideas. Initially he agreed to help. Alex said he was unable to help as the idea was to close to a design they are working on. This is a success in the sense that if a company like Seymour Powell is working on a product similar to mine and can not work with me, then I am on the right track. It is unfortunate that I am unable to work with Alex and gain professional validation. This has gave me confirmation that I am on the right track and that I should progress further with my idea.
98
NATIVE
99
Kyle Loughlin from Native Design said that he liked the idea, however would like to see a wider range of concepts to cater for a wider market. My concept has received more validation from Native and they would like to collaborate and expect to see more. This has spurred me to carry on. From the feedback I will develop other ways this concept could work without using a jacket.

DR MICK HILL
NOTMRT
101
Dr Hill is a volunteer for the North of Tyne MRT and a key person to give validation. He thought the idea could be really beneficial the search and rescue teams as he said that 100% of the people the rescue develops hypothermia. Talking to Dr Hill was a success as he confirmed my insights but give me things to look into, for example, registration systems. On the negative side he did advise me to look into false positives and negative readings. This has gave me confirmation that I am on the right track and that I should progress further with my idea but also look closer at false readings..
102
HEADSET VALIDATION I lay out a range of head wear that could be used to incorporate the sensor and asked Dr Hill which one he thinks would be the most comfortable and best utilised by the MRT team and mountaineers. Out of the 5 items I showed him, He thought the ear warmers would be the best for comfort and security.

KEITH CHEUNG
MONTANE 105
Keith works for Montane as a outdoor clothing designer who has given me advice about the jacket. Keith said the overall concept is good and likes the idea and advised me to consider these points: - Comfort - Where I really need the reinforcement fabric - Weight as they already carry a lot of equipment - Insulation, synthetic is lighter. I will use this advice when I am choosing materials and finalising the concept.
106
107
FURTHER DEVELOPMENT
108
Throughout the project I have been iterating different concepts to develop the right style.
Developing concepts has helped me design to the constraints of the physical material. I will continue to develop and make prototypes of my idea.

KEY FEATURES
112
HEADSET The headset holds the fundamental components for the whole system. A temperature sensor, optical sensor and a communication system.
113
114
JACKET When the core body temperature drops below 35 degrees the lighting system and emergency GPS is activated making the wearer traceable and visible.
115
116
ATTACHMENT The attachment is an idea that came up recently as thick jackets may not be needed in hotter climates. With this in mind it may be good to have a wearable that can be strapped to the body.
117
118
IN A NUTSHELL
119
The system as a whole is a success, the earpiece will contain the correct components to enable the vital signs to be read and send the wireless signal out. The lighting system for the jacket is durable and flexible enough to move with the person and with a low output, a lithium battery will have a long lifespan, and a GPS system can be integrated. Some people may not wear a insulated mountaineering jacket in summer or want to spend more money on a new jacket, so, a wearable device with the same system would be advantageous. Everything has been validated by professionals in mountain rescue and design.
Parts of the initial concept failed, for example, the base layer idea with the sensors in the fabric and the fibre optic lights. However, the failures have in fact, benefited my project in the long run. The concept is now, more refined and ready to be developed further.
