EXPERIENCE

WIRELESS DATA COLLECTION

A client needed to know the real-time loading forces on their implantable device during an animal study. S&V Siu Associates developed a wireless system to measure and collect loading force data in a beating heart for a series of live animal studies. With the technology we were able to monitor and stream real-time data from multiple animals simultaneously. This included using a custom software package that we developed in-house.

CUSTOM SENSOR AND WIRELESS MODULE The heart of the system is the Wireless Module which is designed to be watertight and implantable. The Wireless Module serves as the "node" to which the sensors are connected. Data gathered from the sensors is sent wirelessly from the node to the Wireless Receiver. A strain-gage based custom designed sealed sensor was designed by S&V to measure the load on our client's implantable heart valve device.

WIRELESS REAL TIME MONITORING The Wireless Receiver was connected to a laptop computer running our LiveDAQ™ software enabling us to monitor multiple animal subjects in real-time.

LiveDAQ™ APPLICATION To meet the unique demands of streaming data from multiple nodes, we developed a software application for this project called LiveDAQ™. LiveDAQ™ enables auto data collection at user-specified time intervals and saving the data to files with manageable sizes. The power to control the data collection intervals gave our client control of how and when the files can be downloaded for further analysis.
