Description

The Muscle BioAmp BisCute is an educational DIY electromyography (EMG) sensor kit that enables users to build their own functional biopotential amplifier. By soldering components onto the provided PCB, users gain practical insight into the signal conditioning stages required to amplify sub-millivolt muscle signals to levels readable by standard microcontroller ADCs. The kit is engineered for robustness and learning, featuring a high-input impedance front-end to minimize signal loading and a fixed-gain instrumentation amplifier stage.

Designed for human-computer interface (HCI) prototyping, the BisCute outputs a conditioned analog signal compatible with any development board equipped with an ADC input. Its bandpass filter focuses on the typical frequency spectrum of surface EMG signals, reducing noise from motion artifacts and power line interference. The kit serves as a foundational tool for biomedical engineering students, makers, and researchers exploring muscle activity monitoring, prosthetic control, and gesture recognition systems.

Key Features

  • DIY through-hole PCB kit for hands-on educational assembly and understanding of biopotential amplification circuits.
  • High-input impedance (10¹¹ Ω) ensures minimal signal attenuation from high-source impedance electrodes.
  • Fixed gain of x2420 amplifies microvolt-level EMG signals to a robust 0–3.3V or 0–5V ADC range.
  • Integrated 72–720 Hz bandpass filter rejects DC offsets and high-frequency noise for clean EMG signal acquisition.
  • Wide 3.3V to 30V operating voltage compatibility with single-supply operation for easy integration.
  • Open-source hardware design and example software facilitate customization and rapid project development.
  • Includes all necessary components: PCB, BioAmp cable, Jumper wires, gel electrodes, and an adjustable sensor band.
  • Compatible with a vast range of microcontrollers and ADCs, including Arduino, Raspberry Pi Pico, STM32, and BeagleBoard.

Applications

  • Educational projects for learning biopotential signal acquisition and biomedical instrumentation.
  • Human-computer interface (HCI) prototypes for gesture control and muscle-activated switches.
  • Prosthetic and orthotic device development for myoelectric control signal conditioning.
  • Sports science and rehabilitation monitoring for muscle activity and fatigue analysis.
  • Art and interactive installations using biofeedback and muscle-generated signals.

Frequently Asked Questions

What is the operating voltage range for the Muscle BioAmp BisCute?

The Muscle BioAmp BisCute operates from a single supply voltage between 3.3V and 30V DC. This wide range allows it to be powered directly from most microcontroller boards (3.3V or 5V rails) or from a separate regulated bench power supply, providing flexibility for various project setups.

How do I connect the BisCute to my microcontroller?

Connect the kit's output pin (after assembly) to an analog input pin on your microcontroller (e.g., Arduino A0). The provided BioAmp cable connects the three electrode leads (positive, negative, reference) to the sensor inputs. Power the board from your MCU's 3.3V or 5V pin and a common ground. The output is a conditioned analog voltage ready for ADC sampling.

What type of signals does this sensor amplify, and what is the gain?

This sensor is specifically designed for electromyography (EMG), amplifying the microvolt-level electrical signals generated by muscle contractions. It applies a fixed gain of x2420, boosting these weak signals into a robust 0–3.3V or 0–5V analog output range suitable for microcontroller ADCs. An integrated 72–720 Hz bandpass filter isolates the typical EMG frequency spectrum.

Is soldering experience required to use this kit?

Yes, this is a DIY through-hole soldering kit. You must solder all provided components onto the PCB to build a functional EMG amplifier. If you prefer a pre-assembled version, consider the Muscle BioAmp Candy, which is the surface-mount (SMD) version of this sensor available pre-soldered.

What is included in the package, and what are the electrode connections?

The kit includes the BisCute PCB, all necessary through-hole components, a 50cm BioAmp cable, a pack of 3 Jumper wires, 3 boxy gel electrodes, and an adjustable sensor band. The system uses a 3-electrode configuration: positive (signal), negative (inverting input), and reference (ground) for differential amplification to reject common-mode noise.

Package Includes

  • 1 x Muscle BioAmp BisCute PCB
  • 1 x Set of through-hole components for assembly
  • 1 x BioAmp Cable v3 (50cm length)
  • 1 x Pack of 3 Jumper Cables
  • 3 x Boxy Gel Electrodes
  • 1 x Muscle BioAmp Band (adjustable)
