Device and Know How related to a "Biomedical Platform" for Human Wearable Device

Technology #2009-078

This write-up describes a wearable electronic device, referred to as a “Biomedical Platform”, with the capability of collecting and storing within its own structure and data collected from biomedical sensors attached to a human volunteer or patient (or, in appropriate circumstances, on an experimental animal). The unit is “sensor-agnostic”, in that it can collect data from analog sensors (such as ECG electrodes), or from inherently digital sensors such as tiny MEMS accelerometers. The on-board microcontroller contains both digital input lines and an on-board programmable A/D converter. Data collected in this manner, with sample rates under the control of software residing on the microcontroller, can be formatted into blocks or “frames”, for storage in an on-board FLASH memory chip. Later, the data can be offloaded from the FLASH memory, and transferred either through a small connector (e.g., USB) to a desktop or laptop computer; or can be transmitted wirelessly to an appropriate RF receiver, through a wireless transmitter and antenna incorporated into the unit. The unit also incorporates a small high-technology battery mounted on the reverse side of the small printed circuit board that contains the other components, as well as a high precision time-of-day clock.
