Project 23: Controlling a video game using brainwaves (EEG) In this project, Umang Bansal recorded EEG signals using BioAmp EXG Pill and classified them into 2 states: attentive and relaxed. He further used these states as a trigger to control a car in a video game. Whenever he was attentive the car was moving forward and when he was relaxed the brakes were applied. This is just a demonstration to show you how we can leverage electroencephalography (EEG) signals to develop a Brain Computer Interface (BCI) system to control external devices like a laptop. About the series of projects: We started a series of posts where we share step-by-step guides on how to make various HCI and BCI projects using BioAmp Hardware. So anyone who is a beginner and wants to explore neuroscience can follow along and learn how the bio-physiological signals (EEG, EMG, EOG, EEG) are being produced in the body and how can we use them in making some real-world applications.

Research Paper 3: Shellac-mediated laser-induced reduced graphene oxide film on paper and fabric: exceptional performance in flexible fuel cell, supercapacitor & ECG applications OVERVIEW: Researchers from the highly esteemed Royal Society of Chemistry in UK have published a research paper with an aim to make shellac-mediated laser-induced rGO which can be used in various applications. One of the applications was to make rGO-based dry electrodes with better performance than the standard Ag/AgCl wet electrodes. To check the performance of both the electrodes they recorded ECG signals using BioAmp EXG Pill. RESULTS: 1. Impedance:  i) Ag/AgCl wet electrodes: 49.12 KOhm  ii) rGO-based dry electrodes: 87.85 KOhm (79% more impedance) The lesser the impedance the better. So rGO-based dry electrodes were better. 2. Signal to noise ratio (S/N):  i) Ag/AgCl wet electrodes :17.32 dB ii) rGO-based dry electrodes : 21.5 dB (24% higher S/N) The more the S/N ratio the better. So rGO -based dry electrodes were better. Overall what do you think? Which electrode is better and why? Let us know in the comments. NERD SECTION: To make dry electrodes they used natural shellac (biopolymer) (C25H51COOH) which has inherent long carbon chains that can be leveraged as a potential resource in improving the physiochemical properties of laser-induced reduced graphene oxide (rGO). A versatile 450 nm blue diode laser-produced biopolymer-assisted rGO on environmentally friendly flexible paper and cloth samples. The methodology led to the formation of improved rGO with electrical sheet resistances as low as 2.3 Ohm/Sq.

Research Paper 2: View control system on the basics of EOG Researchers from a university in Ukraine (National Technical University of Ukraine 'Kyiv Polytechnic Institute') have published a research paper where they recorded EOG signals (biopotential signals generated during eye movements and eye blinks) using BioAmp EXG Pill with an aim to increase reliability and give a universal approach on gaze control systems based on EOG to use the data for various real-world applications. To achieve this they recorded the EOG data, did signal processing, and finally analyzed it using 12 different machine learning algorithms to make eye control systems. To validate the research they actually tested it to control a mini robot and even control the cursor on screen using eye movements. RESULTS: Out of 12 machine learning algorithms tested, it was found that random forest machine learning algorithm was best and the data was 91% reliable. The results were tested at the International Multidisciplinary Scientific Internet Conference "The World of Scientific Research" on 20-21 April, 2023.

Research Paper 1: Developing EOG-Based Communication Interface for Quadriplegic Patients Researchers from a university in Pakistan (Institute of Biomedical Engineering and Technology, Liaquat University of Medical and Health Sciences) have recently published a research paper where they recorded EOG signals (biopotential signals generated during eye movements and eye blinks) using BioAmp EXG Pill to create a text and voice-based interpreter for quadriplegic patients suffering from quadriplegia, ALS, and locked-in syndrome. Problems faced by patients: People suffering from the above mentioned conditions are conscious but cannot move or communicate verbally due to complete paralysis of all voluntary muscles in the body except for eye movements and blinking. This restricts patients from communicating. Solution proposed: Eye movements and blinking of the patients can be used as a trigger to help them communicate critical messages like “Call a doctor”. So the researchers have developed a system where they recorded different eye movements and whenever a particular eye movement is detected (like left, right, up, down, blink) it will give us a output in the following ways: 1. Text output on LCD display 2. Audio output from MP3 player 3. Sends a message to the application From today, we are starting a series where we will be sharing the research papers where students/researchers have published something amazing using our BioAmp Hardware.

06.07.24 | Team Meeting This was the biggest team meeting we had since the inception of Upside Down Labs Over the past 2 months, we've welcomed few full-time employees as well as a significant number of summer interns joining for their internships. In this meeting, everyone demonstrated what they have done so far with immense passion and dedication. It was great to see each member contributing actively, showcasing their commitment to help Upside Down Labs grow. The collaborative spirit and innovative ideas presented during the meeting reaffirmed that, together, we have the potential to elevate Upside Down Labs to the next level. A lot of new projects and company updates are coming soon! #upsidedownlabs #startup #teambuilding #entrepreneurship

We crossed 50,000 views on Instructables!! Few months back we started documenting all the projects that can be made using our BioAmp hardware on Instructables and now after 23 projects we have crossed the mark of 50000 views. Seems a little but think about it. We have introduced 50000 people to neuroscience by making easy-to-follow project tutorials that even a kid can follow easily at the comfort zone of their home, school, college, pretty much anywhere. We aim to make neuroscience affordable and accessible to everyone and with these project tutorials we are making it interesting so that more and more people would get their hands on making neuroscience projects like 1. Controlling a prosthetic hand using muscle signals 2. Creating a drowsiness detector 3. Measuring your ECG, heartbeat and heartrate 4. Recording brainwaves or EEG signals 5. Controlling a video game just by thinking 6. Controlling dino game using eye blinks and a lot more This is just the beginning! Let’s make neuroscience easy to learn with Upside Down Labs Link to our Instructables profile is in the comments. #upsidedownlabs #instructables #project #neuroscience
