Sudden Impact Wearables Design Challenge Smart Clothes project Norbert Kovács     1st of December, 2014 — 8th of May, 2015             Preface   First of all, I would like to thanks to element14 and the supporters (Analog Devices, Tektronix, Electrolube, Leeds University) for selecting me as one of finalist of the Sudden Impact Wearables Design Challenge, it is a great pleasure for me. A few words about myself: I were a researcher ...
My project is finished, but already I have ideas for the future development. The most obvious option for development is the smart phone app. The system will vastly "smarter" to using the ICTs: real time control by the coaches, emergency operation, database of records etc. The cost and size of additional circuits can be reduced by SMD technology. The total cost can be reduced and profitable by using high-volume production. It may be necessary the waterproof material of clothes. The further develo ...
The bicycle accidents and injuries have number of reasons: for example the lack of protective equipment; inappropriate speed for the road conditions; abuse of alcohol and drug; and - unfortunately - the inadequate visibility. The main feature of my project is the Fuzzy logic based visibility system. What is the Fuzzy logic? In contrast to the binary (yes-no) logic, there is not sharp boundaries in the Fuzzy logic. A typical fuzzy sets shown below: There is a variable (e.g. temperature, ...
The following devices are needed for the ECG measurement: AD8232-EVALZ board, 3 pieces of gel ECG electrodes, 3 pieces of ECG adapters, 3 pieces of jack plugs, wires, flexible material for the chest strap, microcontroller. Several options have been for the electrode placement. The one of point is the left and right arm, but I rejected this case, because the distance from the heart is greater than the in other options. Receiving of bioelectric signal is better, if measured on the torso a ...
The contraction and relaxation of the heart muscle are controlled by the self-forming and impulse conduction system located in the heart, which is related to the central nervous system through external innervation. The cardiac muscle stimulating electrical pulses start from the right atrium wall of sine knot,  and getting  the atrioventricular bundle through the atrial muscle wall, which is situated in the lower part of the right atrium, directly above the chamber. The atrioventricul ...
In this post I finish the presentation of components of used equipments. Arduino: Compared to the other Arduino boards, the Arduino Micro was the best choice for the smart clothes. It is based on the 8-bit ATmega32u4 microcontroller with 16 MHz clock speed. It has 12 analog inputs and 20 digital input/output pins of which 7 can be used for pulse-width modulation (PWM) outputs. After the filtering, the PWM output can be operated as analog output. The amount of available memory is 32 KB. I ...
In this post I continue the presentation of components of provided equipments. 4. Based on the ADXL362 chip, the following items are provided: a. EVAL-ADXL362Z: It is a 3-axis digital accelerometer board with different,  ± 2 g, ± 4 g and ± 8 g of measurement ranges. It operates in two modes: the first is the measurement mode with less then 3 μA and data rate between 12,5 and 400 Hz, the others is the wake up mode with 270 nA consumption. The output has 12-bit r ...
In the next three days the posts will be about the components of provided and additional equipments. The today's players:   1. AD8232-EVALZ This is a single-lead, heart rate monitor front end is based on AD8232 chip. The functional block diagram is seen below. The measured bioelectric signals are sensed via attached electrodes on the human body. This device can operate with 2 (left, right) or 3 (left, right and driven) electrodes. The two (L and R) electrodes connect to the instrumenta ...
My last post was published a little long time ago, I need to say sorry for this delay. In January I read the related papers and books about ECG and started to make a list of necessary (additional) devices.   At the end of January the standard items were shipped for the Challengers. Unfortunately I had problem with the customs: the package waited 16 (yes, sixteen!) days at the Hungarian UPS Custom Department. Thank to doctorcdf Dr. DeFeo, this administration problem was solved. I was optimis ...
Welcome to in my second blog post! Now I'm going to write a short summary of the structure of the Smart Clothes Project (SCP). There is a word that will be the keyword of my project in the coming weeks (months) : H I T   What does it mean? This is the abbreviation of the main properties of SCP such as Health parameters: the ECG, pulse, body temperature and the impact of the head during the downfall will be measured and logged. The factor of dehydration will be an optional feature if my ...
First of all, I would like to thank to element14 and the supporters (Analog Devices, Tektronix and Electrolube) for selecting me as finalist of the Sudden Impact Wearables Design Challenge, it is a great pleasure for me.   I have to apologise, it was a very busy period in my work and this is the reason of why this post is delayed.   Well, this is an introduction post. A few words about me: I am a researcher at a Chemical Research Institute in Hungary. At this time I am working on a re ...
