Innovation uses ‘stethoscope’ to monitor machine quality, functionality

Researchers at Purdue University have announced a system for efficient, low-cost monitoring for machine health, including overall quality, condition, and operation status.

The Purdue team’s innovation uses audio-based artificial-intelligence technology to monitor the overall conditions of machines in factories, hospitals, and other locations. The Purdue system uses a stethoscope-like system as a sensor and analyzes the data with a neural network-based framework.

“Our solution is to use the concept of doctors listening to a body to assess the initial condition or experts listening to the machine sounds to know what is going on,” said Martin Jun, a Purdue innovator and associate professor of mechanical engineering. “We are using artificial intelligence to train a wide range of sounds from the machine and determine many things about the machine or process autonomously.”

Jun said this system can detect anomalies without being fed a training set and is easier and more cost-effective than accelerometers or acoustic-emission sensors.

The Purdue technology is designed to use internal sounds from a machine to determine the machine status, assess process conditions, diagnose machine conditions, and predict machine failures.

“Since only sound is used, it can be used for a number of different applications,” Jun said. “Having one low-cost sensor for many different purposes can address the current challenges in the area where most of the solutions are quite customized to specific problems.”

      Totally agree Conrad. This is exactly what Innovolo are here for – helping businesses to leverage innovation to help them break through into new markets

  1. This is ingenious new product development for doctors and business entrepreneurs alike. I’m amazed that the stethoscope can pick up so much strictly from sound. The implications from this device are huge for several mediums.

  2. Well like anything over time things grow old and get defects. That is true even for machines. That said if I have not read this at first glace a stethoscope as a tool for a machine Problem solution was quiet weird. Good thing it was cleared. That detector thing is cool.

      Welcome to the world of innovation Louis 😊😊 Often the more successful new product developments are simply an amalgamation of existing technologies rather than a totally new technology (aka invention).

      The importance of preventative maintenance is quite understated I think. Certainly this innovation will help engineers to keep their equipment in tip-top condition.
      Thanks for the comment Meldred.

  3. Artificial intelligence it’s getting very pupular as a way to make things eassier and convenient for people. It’s amazing how it can be used in many areas and has become in a problem solution for many companies.

      Thanks for the comment Danielle.

      There are so many amazing ways artificial intelligence and machine learning are used behind the scenes to impact our everyday lives. AI assists in every area of our lives, whether we’re trying to read our emails, get driving directions, get music, or movie recommendations. Artificial intelligence is already being used extensively in our lives, whether we realise it or not, in social media, digital assistants such as Alexa, Self-Driving And Parking Vehicles, Email communications, Web searches, Stores and services, and even Offline experiences
