cover-sensoronly-790x469Engineer scientists at Stanford have created a submillimeter sensor device that transmits biological health readings wirelessly.  The device is very small, measuring in one realization at only 1 millimeter by 1 millimeter in length and width, and 0.1 millimeter in depth.  It is also highly robust as it works well in tissue environments which are considered “lossy” as they attenuate electromagnetic signals.  FInally the device has been shown capable of reading human pulse waveforms from arterial blood flow as well as intracranial pressure in a mouse.  The novel invention, in guaranteeing continuous, real time readout of health signs, is a significant advance in the area of ultrasmall, wearable sensors.  Such devices are 100 times smaller than equivalent commercially available products, and 10 times smaller than research devices of similar function.
