• Display: An LCD screen or OLED display can be used to show the heart rate in beats per minute (BPM).
• Power Supply: A battery or USB connection to power the system.

Implementation

The implementation process involves several steps. First, you need to connect the PPG sensor to the microcontroller. Then, you'll write code to read the sensor data, filter out noise, and calculate the heart rate. The heart rate is then displayed on the screen. You can also add features like data logging and wireless communication to send the data to a smartphone or computer.

Enhancements

To make your heart rate monitoring system even more advanced, consider adding these enhancements:

• Bluetooth Connectivity: Use Bluetooth to transmit the heart rate data to a smartphone app for real-time monitoring and analysis.
• Data Logging: Store the heart rate data on an SD card for long-term tracking.
• Alert System: Implement an alert system that notifies the user if their heart rate goes above or below a certain threshold.

Project Idea 2: EMG-Controlled Prosthetic Hand

Overview

Another fascinating biomedical electronics project is creating an EMG-controlled prosthetic hand. Electromyography (EMG) is a technique that measures the electrical activity of muscles. By analyzing EMG signals, you can control the movements of a prosthetic hand, allowing amputees to perform everyday tasks.

Key Components

Here are the key components you'll need for this project:

• EMG Sensors: These sensors are placed on the surface of the skin to detect the electrical activity of the muscles.

• Servo Motors: Servo motors are used to control the movement of the fingers and thumb.
• Prosthetic Hand Structure: A 3D-printed or commercially available prosthetic hand structure.

Implementation

The implementation process involves acquiring EMG signals, processing them to identify different muscle movements, and then using these signals to control the servo motors in the prosthetic hand. This requires a good understanding of signal processing and control systems.

Enhancements

To improve your EMG-controlled prosthetic hand, consider these enhancements:

• Machine Learning: Use machine learning algorithms to improve the accuracy and responsiveness of the control system.
• Force Sensors: Add force sensors to the fingertips to provide feedback to the user.

Project Idea 3: Brain-Computer Interface (BCI)

Overview

Creating a Brain-Computer Interface or BCI stands out as one of the more futuristic biomedical electronics projects. A BCI allows direct communication between the brain and an external device. This technology has the potential to revolutionize the lives of people with paralysis or other neurological disorders. It's like reading someone's mind, but in a very technical and helpful way.

Key Components

Building a BCI requires some serious hardware and software skills. Here’s what you'll need:
