1 Smart, soft, stretchable sensors Fabric Sensor Evaluation Kit

2 Fabric Sensor Evaluation Kit Our fabric stretch sensor is tough, rugged, and can be sewn into garments. Its resilience to tearing when overstretched with vigorous force makes it ideal for sports applications. The fabric sensor kit is designed for customers who are prototyping sensing technology in sports, wearables and garment applications. The kit contains a fabric sensor connected to a BTLE circuit protected in a casing. The sensor responds to changes in geometry, and communicates with an Android App to display and record this data

4 Quick Start Guide Get started straight away with the StretchSense fabric sensor. The Quick Start Guide covers how to switch on the sensor, the basics of the Android App, and how to save data to a file. Unboxing The fabric sensor evaluation kit contains: 1 Fabric Sensor 1 Bluetooth LE transmission circuit with casing 1 Coin cell battery (non-rechargeable) + Free StretchSense Android data capture App Getting Started Insert the lithium coin cell battery into the fabric sensor by removing the back cover of the casing and slipping the coin cell into the battery holder. Using the Android App Download the StretchSense Fabric App from the Google Play Store The StretchSense fabric sensor works with an App on your Android device. Go to the Google Play Store to download Fabric Evaluation App from the list of results and install the App onto your device. Once the StretchSense Fabric App is downloaded to your device, run the App. Ensure that Bluetooth is turned on your device. To pair the sensor to the App via Bluetooth press the activation button on the case. After pressing the button, you should observe a light flashing within the sensor. This indicates that the sensor is ready to be paired to the App. Press the Bluetooth symbol on the action bar at the top of the App. Select the entry named StretchSense in the available devices list. If no devices appear, press the button on the sensor again and press Scan in the App. Once the sensor is connected, the bar graph in the App will respond to stretching and deformation of the sensor. Tap on the graph in the App to change its scale. Minimum and maximum can be specified in picofarads. The graph can be automatically scaled by setting the Min to the far left, and the Max to the far right

5 Recording Data To start recording data from the sensor, press the save symbol in the action bar at the top of the App. The App will now begin to record capacitance versus time as measured by the sensor. To retrieve recorded data, connect your Android device to a computer by USB. Ensure that your Android device is enabled as a USB media device. On your computer, browse to the directory of your Android device. Recorded data will be saved in the StretchSense folder. The data is stored in a comma separated value (.csv) file, in pairs of Capacitance (in picofarads), and Timestamp (in milliseconds). Battery The fabric sensor runs on a 3V CR1620 Lithium Metal coin cell battery. The battery life of the sensor is approximately 12 hours during operation. When the battery nears the end of its useful life, a green light will begin to show through the top of the sensor case. This indicates that the battery should be replaced. To remove the battery, remove the back case of the sensor and use a small tool such as a pair of tweezers to gently push the battery out of the battery holder

6 Extension (mm) Load (N) Fabric Sensor Evaluation Kit Fabric Sensor Evaluation Kit Datasheet Sensor Dimensions The sensor has an active sensing zone of 90mm x 10mm surrounded by a 2mm sewable area. Piercing or sewing through the active sensing zone will result in damage to the sensor. Sensor Characteristics 1 Capacitance vs Extension Capacitance (pf) Capacitance vs Load Capacitance (pf) Parameters Maximum extension 80mm (180% extension of active area) Capacitance (un-stretched) 330pF Capacitance (stretched) 440pF Sensitivity 1.38pF/mm Typical Load (un-stretched) 0.0 N Typical Load (stretched) 7.25 N Operating Temperature Range ºC 1. These values are indicative of the sensors. Individual sensors may vary

7 Safety Lithium Metal Batteries Warning WARNING: Read before charging or using battery IMPORTANT SAFETY INSTRUCTIONS AND WARNINGS You must read these safety instructions and warnings before using or charging your batteries. Lithium Metal batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly. StretchSense does not assume any liability for failures to comply with these warnings and safety guidelines. By purchasing this battery, the buyer assumes all risks associated with lithium batteries. If you do not agree with these conditions, return the battery immediately before use. General Guidelines and Warnings Do not insert batteries in reverse. Observe the polarity markings on battery and equipment Do not short-circuit batteries - Do not ingest batteries Do not charge batteries Do not force discharge batteries Do not mix batteries Do not overheat batteries by exposure to high temperatures and direct sunlight. Do not weld or solder directly to batteries Do not dismantle batteries Do not deform batteries Do not dispose of batteries in fire A battery with a damaged container should not be exposed to water Do not allow children to replace batteries without adult supervision Keep batteries out of the reach of children. In case of ingestion of a cell or battery, the person involved should seek medical assistance promptly. Do not encapsulate and/or modify or alter batteries Exhausted batteries should be immediately removed from equipment and disposed of In the event of suspected damage to the battery, you must remove battery for observation and place in a safe open area away from any combustible material. Physically damaged cells could erupt into flame and after sufficient time to ensure safety, should be discarded responsibly in accordance with best practice in your area

8 Do not allow batteries to overheat at any time. Batteries which reach greater than 60 degrees C (140 F) will usually become damaged and will catch fire. Do not allow batteries on or near combustible materials including paper, plastic, carpets, vinyl, leather, and wood. Do not over discharge, doing so will damage the battery. Do not expose battery to water or moisture at any time. Do not store battery near open flame or heater. Always store battery in a secure location away from children. CAUTION: batteries may be hot! Operating Temperature: 0 C ~ 60 C Before Use Carefully inspect the battery for even the smallest damage. Make a visual inspection of the battery. Look for any irregularities. If any damage to the battery is found, do not attempt to use the battery. Remove battery for observation and place in a safe open area away from any combustible material. Storage & Transportation - Store unused batteries in their original packaging and keep them away from metal objects which may shortcircuit them. Storing unpackaged cells together could result in cell shorting and heat build-up. Store and display batteries in there original packaging in well ventilated, dry and cool conditions. Avoid storing or display batteries in direct sun or in places where they get exposed to rain Do not stack battery cartons on top of each other exceeding a specified height. The height is clearly dependent on the strength of the packaging. As for general rule this height should not exceed 1.5 m for cardboard packages or 3 m for wooden cases. The above recommendations are equally valid for storage conditions during prolonged transit. Thus, batteries should be stored away from ship engines and not left for long periods in unventilated metal box cars (containers) during summer. Store, in a fireproof container. Store battery at room temperature between 5 and 26 degrees C (40 and 80 F). Storing battery at higher temperatures may cause damage to battery and possible fire. Use caution to avoid puncture of the battery. Puncture of batteries may cause fire. Damaged Batteries Do not have contact with a leaky/damaged battery directly. Do not allow the electrolyte to get into eyes or on skin. Wash affected areas immediately if they come into contact with electrolyte
