Fun Project (Wearable Electronics): Shoe Insole Pressure Sensing for Dynamic Foot Pressure Analysis
In this video we show dynamic foot pressure mapping using our MP2512 smart sensor insole development kit.
MP2512 comes with two FSR (Force Sensing Resistor) sensor insoles which are insole shaped FSR matrix sensors. On the sensor 160 pressure sensing pixels are disposed to provide high resolution footprint force image.
This product also include Snowboard 2 – low cost pressure mapping electronics.
With Kitronyx API, a developer can easily capture foot pressure distribution data and send it to another application via TCP/IP.
It's the era of IoT (Internet of Things). Here we user force sesnsitive resistors (FSRs) to build an smart warehouse prototype. In this prototype, we use Snowboard 2 and a few single-zone FSR sensors.
In this study, we share our latest work for a research institute who needs pressure mapping sensor for animal behaviour analysis.
The system is composed of MC1600 and MS9760 FSR matrix sensor sensitive enough to assess motor performance in rats and mice.
Footprints of mice are collected and transmitted by MC1600 and our analysis software visualizes and saves data for data analysis by our customers
Snowboard 2 is a low cost data acquisition electronics for FSR matrix sensors. It can be used as a standalone device as well as an Arduino shield. In this demo video, Snowboard 2 is combined with Arduino Uno, SeedStudio Bluetooth Shield 2.0, a gas sensor, and a temperature sensor. Arduino collects all sensor data and transmit them to host PC via Bluetooth network.
Sense Force Touch
This week we're happy to show you a new force multi touch feature implemented with MC1509 force controller and MS9712 FSR matrix sensor!
We built this feature according to requirements from one of our clients who want to embed this interesting force touch function into their project.
Animal Foot Pressure Mapping
Prof. S. Y. Heo at Chunbuk university shared an interesting video. He uses two Snowboards to measure pressure distribution of rear feet of a dog. You can see a live video here.
Thanks Prof. Heo!
PS: If you are interested in using multiple Snowboards, see this tutorial.
3DPad from Ootsidebox
We have an interesting opportunity to evaluate Ootsidebox's 3DPad. 3DPad is an Arduino shield to implement a touchless gesture controller.
Ootsidebox blog has comprehensive material to start and play 3DPad. For your convenience, useful links are collected below with some comments.
3DPad Getting started guide
- In order to make 3Dpad work correctly, you need a 12V DC power supply (mandatory). 3DPad won't work correctly without it. After you upload Arduino firmware and launch a serial monitor you will see something like this which shows that 3DPad is working.
3DPad's demo software - Processing
- After you setup 3DPad, you may want to visually see how it works. 3DPad comes with a visualization software built by Processing environment. Although Processing 2.1.1 is mentioned in the link, Processing 2.2.1 also works well with 3DPad.
- In our test, the Processing code outputs following error message. However, it does not affect the operation of the software. Just ignore it and go forward to connect to 3DPad.
Now hover your finger above the pad and the visualization software will visually show your 3D gestures.
3DPad's demo software - VB6
- This visualization software is written in VB6. Since it only supports French at this time, we skipped testing it.
And here are more links for your deeper understanding of 3DPad.

Thanks Jean Noel to share this gorgeous device!
