Current diagnostic equipment sensors have great difficulty detecting human vital signs below 10 cycles per second (Hertz) due to poor sensitivity and signal to noise ratio (SNR). Current sensors in the 5-10 Hertz frequency bandwidth have extreme low sensitivity or low SNR and therefore require complex software algorithms and costly electronics to extract useful information – the absence or presence of disease. In addition to the poor SNR at 5-10 Hertz, current sensors are unable to detect human vital signs below 5 Hertz (0-5 Hertz) – thus providing no information in the sub 5 Hertz region.

 

Yet, much data is produced by the human body in the 0-10 Hertz bandwidth but no useful sensor system diagnostic equipment is available for detection. This limitation is extremely unfortunate since there is a plethora of information provided by human vital signs at these extreme low frequencies. Therefore with current equipment, the medical practitioner is provided only a portion of the total data the human body provides regarding its performance – possibly leading to an incorrect or incomplete diagnosis.

 

GII’s sister company, Precision Sensors and Instruments, Ltd. has developed the Smart Medical Sensor System (SMSS), a variation on the SSS - a sensor technology specifically for medical applications. The SMSS has several advantages over current medical diagnostic equipment. With its high resolution, sensitivity, SNR and wide bandwidth capability, it can be utilized in non-invasive medical diagnostic equipment to detect abnormalities at frequencies never before utilized – 0.001 to 10 Hertz. The high SNR capability provides strong, uncluttered human vital sign signals for extraction of useful information without the need for complex software algorithms and the associated costly electronics.

​

The ability to acquire human vital sign signals with high sensitivity below 10 Hertz is revolutionary and provides medical practitioners with data never before seen. This disruptive new sensor technology opens up new avenues of research to form the basis for the next generation of precision, full bandwidth, high sensitivity medical diagnostic equipment.

​

Diagnosing different diseases will require different interfaces and different software algorithms. The system engineering and integration requirements for diagnostic equipment utilized for the heart or brain or other organs will be decidedly different. As a result, these changes will be accommodated by GII’s custom designed Integrated Smart Medical Sensor System (ISMSS) thus allowing the SMSS to remain the same for different applications. A common SMSS for all applications leads to production and cost efficiencies.
