Stretch Sensors for Measuring Human Body Motion

Soft and light sensors that provide consistent stretch data

Stretch Sensors are Based on
Stable Underlying Physics

What is a Stretch Sensor?

A stretch sensor is a smart elastic band that provides an accurate measurement of deformation when stretched.

When sewn or glued onto fabric a sensor can measure how the human body moves
supplying powerful data and
analytics for new wearables.

How Does a Stretch Sensor Work?

StretchSense sensors are soft capacitors that can be stretched or squeezed. As a sensor’s shape changes, the capacitance of the sensor correspondingly rises and falls.

The capacitance of a sensor is tightly related to deformation and minimally affected by environmental factors.

Why are Stretch Sensors Useful?

Stretch sensors have stable underlying physics giving repeatable and accurate measurements with almost no drift.

We provide a variety of circuits, apps, algorithms, and software so that you can build and evaluate your own wearable.

Choose From our Three Sensor Lines

Stretch Sensor

Stretch sensors accurately measure stretch, comfortably conform to the body, and are easy to sew or glue into clothing.

Measure changing joint angles, circumferences, and lengths on people and other soft objects.

Splay Sensor

Splay sensors are multisegmented to pick up bending on different parts of the body.

Measure the bending and the spread of fingers and the
thumb

Compression Sensor

Compression sensors are soft pads that deform in shape when compressed.

Measure pressure under the foot or
between an object and the
body

Connect Your Sensors to Quality Circuits

10-Channel Developer Circuit

For sensors: Stream sensor data from up to ten sensors in real-time over Bluetooth. The 10-channel circuit is a hackable board for validating new product concepts quickly. Remove the Bluetooth adaptor and instead replace it with your own PCB or Arduino to test inclusion of other sensors.

Specs: 40ms/25Hz, BLE Shield, SPI Slave to system Master, 29mm x 25mm x 17mm, 10×2 2.54mm pitch headers

16-Channel Glove Circuit

For gloves: Use our miniature glove circuit with built-in battery charging for hand motion applications. Stream up to sixteen channels at once. Comes with expansion ports for data logging, timecode sync, and IMUs.

Specs: 15ms/67Hz, I2C x2 for IMU/digital sensor inputs and sensor data outputs, SPI x1 for SD card, UART x1 for Timecode synchronisation, 29mm x 15mm x 4mm, Zif Connector

Pair with our Apps

For Sensors

View raw sensor data streaming from our 10-channel circuit in real-time. Record data inside the App and send it for post-processing. Characterise sensor response, debug prototypes, and build basic applications.

Google Play, App Store, Github

For Gloves

Animate hand motion in real-time by connecting your glove to our Unity and MotionBuilder applications. Calibrate gloves and generate machine learning weighting matrices. Stream and save both raw sensor data and calculated joint angles.
