# Title
Teaching Heat to Student

# Problem
The need for an effective and engaging educational tool to introduce elementary and middle school students to fundamental concepts of heat transfer and thermal energy conversion.

# Solution Overview
We propose the design and manufacture of an integrated thermal experiment platform that provides a safe and hands-on environment for students. The platform will include visual demonstrations of heat conduction and convection, a coating for thermal radiation visualization, and an introduction to thermoelectricity.

# Solution Components
## Subsystem 1
Use a metal rod with one end heated and temperature sensors to detect every temperature on certain position, then visualize it on a computer. And we can use another hollow metal rod with fluid in it, detect and visualize the temperature in same way and show the influence of convection.

## Subsystem 2
Demonstrate the principle of electric heating material which could generate current when people put their hands on it and light up LEDs displaying 'ZJUI'.

## Subsystem 3
Design a coating material which could reflect certain wavelength of a light source and allow the electronicmagnetic wave from human to pass through. Demonstrating a scenario that people could feel cool with this material when received heat source radiation.

# Criterion for Success
- Engaging and safe educational experience.
- Clear understanding of heat transfer concepts by students.
- Successful demonstration of thermal radiation and thermoelectricity.

Low Cost Myoelectric Prosthetic Hand

Featured Project

According to the WHO, 80% of amputees are in developing nations, and less than 3% of that 80% have access to rehabilitative care. In a study by Heidi Witteveen, “the lack of sensory feedback was indicated as one of the major factors of prosthesis abandonment.” A low cost myoelectric prosthetic hand interfaced with a sensory substitution system returns functionality, increases the availability to amputees, and provides users with sensory feedback.

We will work with Aadeel Akhtar to develop a new iteration of his open source, low cost, myoelectric prosthetic hand. The current revision uses eight EMG channels, with sensors placed on the residual limb. A microcontroller communicates with an ADC, runs a classifier to determine the user’s type of grip, and controls motors in the hand achieving desired grips at predetermined velocities.

As requested by Aadeel, the socket and hand will operate independently using separate microcontrollers and interface with each other, providing modularity and customizability. The microcontroller in the socket will interface with the ADC and run the grip classifier, which will be expanded so finger velocities correspond to the amplitude of the user’s muscle activity. The hand microcontroller controls the motors and receives grip and velocity commands. Contact reflexes will be added via pressure sensors in fingertips, adjusting grip strength and velocity. The hand microcontroller will interface with existing sensory substitution systems using the pressure sensors. A PCB with a custom motor controller will fit inside the palm of the hand, and interface with the hand microcontroller.
