Self Powered Biosensors

In response to the DHP 12-010 self powered biosensor solicitation, MaXentric proposes the VitalH system. Acknowledging the difficultly in creating a completely self-powered bio-sensor system that wirelessly transmits vital sign information, MaXentric has developed a solution which is extremely power efficient and minimally invasive. The VitalH garment continuously senses full ECG waveforms in a comfortable contactless manner. The ECG data is wirelessly transmitted to a display device (smart phone, tablet, etc) which uses the VitalH software to calculate, store and display heart rate, respiratory rate and full ECG waveform data. Using ultra-low duty cycle transmission, power consumption of the wireless transceiver is minimized. This technique reduces power requirements to levels at which operation of the entire system can be sustained via harvested power. Power for system operation is harvested from respiratory effort. This is an important advantage of the VitalH system. Since power is provided by one of the vital signs being measured, the system ensures that energy will always be available to process and transmit sensed data. Through the use of advanced software and hardware techniques the VitalH system is free of many of the issues that plague ECG sensor systems.
