Project name: Conductive Fabric Gesture-Control Sleeve

Team members: Guneev Lamba (glamba2), Mrunmayi Deshmukh (mdeshmu2), Stephanie Wang (swang166)

Introduction: Our project idea is inspired by a couple things. First is our curiosity in wearable tech. Second is Jacquard, a project by Google and Levi’s (https://atap.google.com/jacquard/).

Our project idea is to integrate the gesture control into a fabric sleeve/wristband. Inspired by Jacquard, this wristband will have a capacitive or resistive touch sensor system designed on fabric using a conductive thread pattern that can detect simple gestures. These would be communicated through an RF module to a receiving end that would be able to perform certain actions depending on the gesture pattern. The goal is to develop a product whose functionalities and ease-of-use can be naturally integrated into daily life.

Target use case: This product can be potentially used by bikers to control simple functions on their smartphones like music and phone calling.

Gestures to implement: 1) Swipe up, 2) Swipe down, 3) Single tap, 4) Double tap
Our touch sensor system will be required to distinguish between the above gestures. We will also implement activation/deactivation feature which can be used to turn off the sleeve when not in use.

Expected modules:
1) Touch sensor system (capacitive or resistive) designed on fabric using conductive thread,
2) RF module - Bluetooth or Wifi,
3) Flex PCB to integrate with the touch sensor system
4) Control module - Microcontroller & PCB

Resources: We have consulted with Skot Wiedmann who has experience with touch sensing systems and can be a great resource. He has also offered to be our mentor for this project. All three team members are EE’s with backgrounds in signal processing and power systems, and have experience with other applications of conductive thread.

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.

Description:

We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
