Hello! my name is Mohammed Hasan and I am an aspiring biomedical engineer with a passion for assistive technology and biomedical research. My projects and experience have taught me valuable skills particularly in the areas of physical fabrication techniques as well as in prototyping and design. Some highlights of my work are depicted below.
The device is an exoskeleton designed to fit over a person’s hand to assist those with reduced hand functions to grip objects they might use on a daily basis, while simultaneously rehabilitating the hand. The device consists of a 3D printed exoskeleton that can flex the fingers using springs, and extends the fingers using a servo motor controlled by an Arduino UNO microcontroller.
Individuals with limited hand mobility experience difficulty in grasping and manipulating objects due to changes in their prehension patterns and their range of motion. This deterioration in hand function makes daily tasks involving precision dexterity, such as holding cutlery, opening doors, doing buttons, and holding cups, difficult to accomplish. By both making these tasks easier and decreasing the reliance of these individuals on caregivers and physiotherapists, DynaGrip puts the control back in the hands of the people, Literally!

Clickmxte is a peripheral designed to work with computers via a standard USB connection, and requires no additional setup, just plug and play! The device consists of a 3D printed housing and lever which can click based on pronation and supination. It is powered by a Raspberry Pi Pico Microcontroller and programmed in Circuitpython.
Clickmxte is aimed towards individuals with connective tissue disorders which hinder their fine motor skills, preventing them from using traditional peripherals like mice and keyboards. By taking the inputs which are normally controlled by buttons and the scroll wheel and remapping them to gross movements of the arm at the elbow and forearm, the door is opened for these individuals to access technology independently.

A key skill which I have developed as part of my work is 3D-printing and 3D-modelling. This is a skill which I have used in a variety of applications including most recently as part of my work on DynaGrip, an assistive device to improve hand mobility which I worked on as part of a group project in my Health Solutions Design Projects III course. The majority of my contribution came from both modelling components of the finger assembly and subsequent fabrication using 3D-printing.
