Prototyping with Applied Science: Design and build a bite sensor

Join me in brainstorming and building a bite force sensor that allows paraplegic musicians to smoothly control an expression pedal. This video will include construction tips and tricks, methods, material selection, and a little design philosophy.

Tiny linear potentiometer used in final design: Spring-loaded linear potentiometer: Sil-Poxy for bonding silicone rubber to itself and other materials: Sorta Clear 40 - Platinum-cure silicone molding: Light-cure 3311 adhesive: (expensive, but this tube will last a long time) Blue lasers on eBay "5mW" *wink* Braided shield, highly flexible, 4-conductor cable: Fabric reinforced silicone sheet: Mechanical CAD on github: Support Applied Science on Patreon:


  1. It seems like the pneumatic prototype was a means for you to ‘visualise’ the user experience of the device. I think in a situation where you are more familiar with how the device will be used (e.g. you are building something for your own use) it might be easier to rule out otherwise appealing design approaches.

    In any case, brilliant video, and very elegant solution.

  2. Hi. I am a delighted follower of your YT channel. I wonder if you could be interested in the ultra precision voltage reference (LTZ100) described in EEVBLOG. I have read the massive amount of messages, and i wonder if The box that contain the Voltage reference , can be improved if it is sealed into a vacuum box with temperature sensors inside and outside which can control a pwm connected to a Peltier cell in order to keep a constant temp, 25deg e.g.. Since i don't have any idea how to do it, i kindly suggest you that challenge.
