Low-Power BioZ AFE by Analog Devices Shrinks Size for BioZ Monitoring

WILMINGTON, Mass. – March 8, 2022 – Reduce the size and extend the life of bioimpedance (BioZ) remote-patient monitoring (RPM) devices with the MAX30009 low-power, high-performance BioZ analog front-end (AFE) from Analog Devices, Inc. (ADI). For developers of small, battery-powered, continuously wearable devices, this AFE on a chip offers clinical-grade vital sign measurements of bioimpedance analysis for patient health assessment for wellness wearables and medical-grade patches.

Many vital signs monitors, chest patches, stress monitors, BioZ and wearable healthcare devices must operate on a small battery as part of small, compact designs that emphasize convenience and comfort. The MAX30009 is a low-power design with a range of options to enable use-case power optimization that reduces the draw on tiny batteries, thus extending the operational life of BioZ wearables. It reduces power consumption by 62 percent compared to the closest competitive product to extend measurement periods for body-worn patches, and vital signs monitoring devices. The highly integrated AFE is also 30 percent smaller than the closest competitor, allowing designers to reduce the size of vital signs measurement devices, making them more comfortable and convenient for consumers and patients.

Bioimpedance analysis devices are popular and convenient ways healthcare professionals measure body fat percentage and body composition (such as respiration and impedance cardiography.) The MAX30009 monitors a comprehensive range of BioZ modalities through simultaneous I and Q measurements, 2-electrode (bipolar) and 4-electrode (tetrapolar) configurations. This enables flexible inputs for BioZ modality measurements as well as a wide range of sample rates to support various medical BioZ measurements. A wider range allows more profound insights into patient health by measuring respiration rate, galvanic skin response and electrodermal activity, body composition and fluid analysis, bioimpedance spectroscopy, impedance cardiography and plethysmography.

MAX30009 BioZ AFE Key Features:

  • Smaller Size: high level of integration enables 30 percent smaller design to reduce size and improve patient comfort
  • Lower Power: Consumes 62 percent lower power to reduce power
  • High-Performance: Measuring from both I and Q channels, 2-electrode and 4-electrode configurations as well as sample rates from 16sps to 4ksps and a wide frequency range of 16Hz to 891KHz

 

“Healthcare wearables are saving lives by measuring the health of millions of patients with a broad range of conditions. Through bioimpedance (BioZ), medical professionals and scientists have been able to gain access to a new plethora of clinically meaningful physiological parameters that now can directly benefit consumers, including stress, hydration levels, and early detection of cancer,” said Dr. Benjamin Sanchez, Assistant Professor of ECE at University of Utah and bioimpedance expert. “I use devices like the MAX30009 AFE in my research and they play a valuable role in making BioZ monitoring more ubiquitous for healthcare device designers and fitness consumers.”

Demo: Achronix Speedster7t 2D NoC vs. Traditional FPGA Routing

Sponsored by Achronix

This demonstration compares an FPGA design utilizing Achronix Speedster7t 2D Network on Chip (NoC) for routing signals with the FPGA device, versus using traditional FPGA routing. The 2D NoC provides a 40% reduction in logic resources required with 40% less compile time needed versus using traditional FPGA routing. Speedster7t FPGAs are optimized for high-bandwidth workloads and eliminate the performance bottlenecks associated with traditional FPGAs.

Current Sense Resistor - WFC & WFCP Series

Sponsored by Mouser Electronics and Vishay

If you are working on a telecom, consumer or industrial design, current sense resistors can give you a great way to detect and convert current to voltage. In this episode of Chalk Talk, Amelia Dalton chats with Clinton Stiffler from Vishay about the what, where and how of Vishay’s WFC and WFCP current sense resistors. They investigate how these current sense resistors are constructed, how the flip-chip design of these current sense resistors reduces TCR compared to other chip resistors, and how you can get started using a Vishay current sense resistor in your next design.
