There are many smart devices available to us that are able to detect our heart rate and other bio data by using a method called photoplethysmography (PPG), a concept of how blood is able to reflect red light while absorbing green light. The device can detect the amount of blood flowing, so when there’s more

Air Quality Prediction is a project that balances Arduino development and Machine Learning. I have always found the world of machine learning captivating but was never able to run models on real-time data. Arduinos provide the solution with a vast array of sensors supported on their microcontrollers. As a result, I knew that I wanted
For this project, I wanted to create an interaction that would seamlessly combine the natural and the digital to make a cohesive project which sparked wondering and curiosity. I was inspired by the idea of a fairy garden and wanted to make a plant that would produce the same enchantment. I planned this project around

After playing around with Freetouch to make a knitted fabric switch, it was found that the sensor reading varied depending on the type of interactions. For example, prodding the fabric resulted in a much lower sensor reading than grabbing the fabric. Based on this observation, I played around with how to use Freetouch and knitted

The temperature sensor for Arduino is a fundamental element when we want to measure the temperature of a processor of the human body. The temperature sensor with Arduino must be in contact or close to receive and measure the heat level. That’s how thermometers work. These devices are extremely used to measure the body temperature

Having made a lot of wearables as an engineer, advisor, and through replication, there’s one irritation that I find consistent with a lot of systems (mine included) – components (typically sensors & actuators) can’t be maneuvered to the wearer’s preferences. To begin to think about how to solve this issue, I’ve made this prototype system

In a couple of weeks, some students will visit my lab (Craft Tech Lab) to learn more about wearable technologies. I wanted to build a quick and simple application of a sensor and vibration motors for them to play around with and rough up. While this project could be made into a wearable mask, due

N.B. this is new and still being tested. This sketch demonstrates several examples of single-channel filters for processing sensor data. The filter functions are purely numeric operations and not dependent on any Arduino-specific features. This supports offline testing, as they can be compiled for debugging and evaluation on a normal desktop computer. The code is
