Frequently Asked Questions
WHAT ARE THE DISCOVERY KITS FOR?
Our Discovery Kits are for R&D engineers and product developers to discover new ways of utilizing our stretch sensing technology for smart clothing, sports and VR/AR applications. The kits contain a range of sensing elements to enable rapid prototyping. Your design teams will have plenty of sensing elements to play with - twist them, stretch them, have fun! Get creative!
WHY DO I NEED A LARGE NUMBER OF SENSING ELEMENTS?
We don't want your prototyping experience to be limited by the number of sensing elements included in the kit. Having more sensing elements offers more room for experimentation. You have the freedom to apply many sensing elements to more than one project and share them with team members.
WHAT IS THE STRETCH SENSING DISCOVERY KIT?
The Stretch Sensing Discovery Kit provides everything you need to test out your wearable idea. The 10 Stretch Sensing Elements allow you to experiment with sensor placement on your prototype and can be easily attached for more robust testing and development.
WHAT IS A CIRCUIT CHANNEL?
Typically each channel can support one sensing element. Therefore, a 10-channel circuit can connect up to 10 sensing elements. We also offer a Bluetooth® Adapter that allows our 10-channel SPI sensing circuit to connect via Bluetooth® Low Energy to a mobile device.
CAN I CONNECT MULTIPLE BLUETOOTH® CIRCUITS TO THE SAME DEVICE?
Yes, this is dependent on the device specifications and Bluetooth® platform used.
CAN I MAKE MY OWN INTERROGATION CIRCUITRY TO USE YOUR SENSING ELEMENTS?
We advise using StretchSense circuitry to get the best results and save on development time. There are a number of software and electronics challenges associated with sensor interpretation. Our software team has solved these issues and is continuing to upgrade our sensor interrogation methods.
HOW CAN I VISUALIZE SENSING DATA IN REAL TIME ON MY COMPUTER?
Using the record function on our Data Visualization App, you can save data on your mobile phone and later transfer it to your computer.
CAN I MAKE MY OWN ELECTRONICS?
We advise integrating StretchSense circuitry into your own electronics to get the best results and save on development time.
WHY ARE YOU SUPPLYING THE 10-CHANNEL CIRCUIT WITH THE KIT?
Each 10-channel circuit allows you to connect up to 10 sensing elements at a time. Our 10-channel circuits turn the raw analog signal from the sensing elements into digital data you can use.
WHAT CUSTOMIZATION WORK DOES STRETCHSENSE DO?
We make complete sensing systems that are ready to be integrated into our customers’ products. We make the sensing elements, connections, circuitry and data capture software, and are able to customize in each of those of areas.
WHAT IS THE BEST WAY TO WORK WITH STRETCHSENSE?
We aim to ensure our customers have the fastest journey from the discovery of sensing technology to product prototyping and mass production. A great starting place is to try one of our Discovery Kits, which are designed to be generic sensing kits for engineers and product developers to start testing with.
I’VE TRIED THE DISCOVERY KITS, AND HAVE AN APPLICATION I WANT TO PROCEED WITH. WHAT DO I DO NEXT?
Get in touch with your sales rep or drop us a line at firstname.lastname@example.org. We'll talk you through the product development stages as well as how we manage client information. We understand how important your ideas are, and we have strict policies in place to keep them safe.
WHAT INDUSTRIES ARE CURRENTLY USING STRETCHSENSE?
Our customer base spans a diverse range of industries. Some examples include wearables, sports and fitness, VR/AR, healthcare, rehabilitation, robotics, automotive, aerospace, fashion, music, movies and gaming.
Our customers use our sensing elements to measure body motion, the interactions between humans and devices, and subtle changes in soft industrial objects.
MY APPLICATION REQUIRES REGULATION, HOW CAN I ENSURE THAT THE SENSORS MEET MY REGULATION EXPECTATIONS?
Our sensors are used in a broad range of applications and industries. Please get in touch with email@example.com with your specific regulation requirements.
WHAT IS YOUR BUSINESS MODEL?
StretchSense is your supplier of Application-Specific Sensing Arrays (ASSA) and we work with you to bring your idea to life through three phases. Discovery Kits and our Consulting Services assist you during the discovery phase to turn your idea into a design and create a proof-of-concept mockup.
Our Prototyping Services assist you during the prototyping phase to turn this proof-of-concept into a more refined Prototype Sensing Array (PSA), to test and iterate until you are ready for mass-manufacture. Application-Specific Sensing Arrays (ASSA) are the stretch sensing systems we supply based upon your entire journey, and is the turnkey solution entirely customized for you.
WHO ARE YOUR CUSTOMERS?
We work with over 300 clients in 28 countries who develop cutting-edge applications in various industries. We maintain strict confidentiality agreements with our customers, and understand the importance of being first-to-market to maintain a competitive edge.
WHAT ARE STRETCH SENSING ELEMENTS?
Our sensing elements are like smart rubber bands. They are flexible capacitors that are soft, stretchy and can easily be embedded into clothing or devices.
WHAT CAN STRETCH SENSING ELEMENTS MEASURE?
Stretch sensing elements track how their geometry deforms as a measure of electrical capacitance. When they are attached correctly to a soft body of material - such as clothing or on a person’s body - the sensing elements provide precise information about how that object or person’s body is moving through the sensor’s geometry changes. This can allow athletes to receive feedback on technique, consumers to interact with augmented reality devices in new ways and healthcare providers to track the recovery of their patients.
WHAT IS THE PRICE OF SENSING ELEMENTS IF I WANT TO PURCHASE IN VOLUME?
Stretch sensing elements are made of low-cost materials so customers can enjoy economies of scale at mass production. We have three categories of production that signal large drops in sensor price for our customers – labor-based, machine-based and commodity production. These categories occur at different volumes based on the specification and quantity.
WHAT IS THE DIFFERENCE BETWEEN FABRIC AND SILICONE SENSING ELEMENT PRODUCTS?
Both our fabric and silicone sensing elements are suitable for a wide range of applications, but each sensor type is particularly suited for certain applications.
Our silicone sensing elements are useful for consumer wellness applications where they need to be pressed up against the skin, or in applications where they are adhered directly to or integrated into rubber-like materials. Our fabric sensors are ideal for wearable applications where the sensors are sewn into garments.
WHAT IS SHIELDING? WHY IS IT USEFUL?
StretchSense develops shielded silicone and fabric sensing elements for customers to use in prototyping. Shielded sensing elements have a ground layer on the top and bottom of the sensor so that the signal layer in the middle is resilient to electrical noise. Shielded sensing elements are highly recommended for any application that requires the sensor to be close to the human body. The shielding reduces the effect of electrical fields emanating from the human body on the accuracy of the sensor data.
