Trill Flex: Flexible Touch Sensing For Makers

Trill Flex brings flexible sensing to your interactive projects. Now available on the Bela Shop: shop.bela.io/collections/tril...
There are two parts to Trill Flex: the base (where you'll find the Trill chip and a high-density connector) and the flexible sensor (made from flex PCB). The Trill Flex sensor easily conforms to curves, bends, corners and more, giving you the freedom to create projects with touch surfaces that are virtually any shape. Trill Flex ships with a one-axis, multi-touch bar sensor, and connects to your Bela system or microcontroller via an included Grove-to-pin connector.
The flexible sensor is detachable, meaning that you can swap it out for a flexible sensor that you created. We've created a tutorial so you can learn how to create flex PCB sensors for Trill flex: learn.bela.io/flex-design
Every Trill Flex also ships with a unique discount code for $20 off flex PCB printing from OSHPark.com.
++ About Trill ++
Trill is a family of touch sensors that launched on Kickstarter in 2019. Inspired by the way we use our hands to interact with the world, Trill sensors use capacitive touch technology to make it easy to add high-resolution, natural touch interaction to your interactive projects. Find out everything you need to know about using Trill at learn.bela.io/trill
Trill was designed for Bela but is compatible with any platform that supports I2C communication, such as Arduino, Raspberry Pi, Teensy and more. Every Bela and Bela Mini system ships with a Trill library as well as lots of examples (including visualisations using our GUI integration). Libraries and examples for other platforms are available on our Github repo.

Hi, Bela, I have two questions regard to the flexible capacitive sensor applications. 1. As you mentioned, the sensor unit can be much smaller than finger tip like "trill hex", which has sensor size of 3x3mm. Is it possible to make such small sensor on the flexible platform (polyimide flexible PCB) 2. If I want to make wearable devices with the sensor, then one side will touch with human body while the other side serves as sensor. But according to my experience, it will have significant parasitic effects toward the sensor. One viable solution is active shielding. Do you have some active shielding channel available? Or do you think the sensor will still perform well in that situation? Thank you!

this is interesting, but it is a little hard to find its application.

[@awaisahmadsiddiqi6505]

Can it detect bends ?

[@oromoiluig]

unfortunately not

[@user-vl6bh1jt6q]

can you cut this sensor?

[@oromoiluig]

yes you can.
