Digital media designer-artist, theorist and curator Valérie Lamontagne has an incredible wearable technology resources page that lists the who’s who and who’s upcoming in the wearable technology and eTextile field. She has even grouped designers and organizations into very interesting categories such as “Context as Prerequisite”, “The Garment as Amplifier of Fantasy”, and “Material Witness”.
I have personally reached out to some of the manufactures and found them to be very helpful.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
