Wireless probes for monitoring blood flow in biological tissue

A wearable probe for monitoring blood flow in biological tissue comprising:

• a sensor module configured to be positioned proximate the tissue to be monitored, the sensor module comprising:
• at least one transmission source configured to transmit signals into the tissue at a source position;
• and
• at least two detectors configured to detect a result of the signals transmitted by the at least one transmission source, the at least two detectors including a first detector positioned at a first separation distance from the source position and a second detector positioned at a second separation distance from the source position;
• and
• a control module electrically connected to the sensor module, the control module comprising:
• a controller, the controller including:
• a processor;
• a memory including instructions executable by the processor;
• and
• a communications interface,
• wherein the instruction, when executed by the processor, cause the processor to control the sensor module to transmit signals into the tissue and detect results of the signals with the at least two detectors, receive the detected results, store the detected results in the memory, and transmit the detected results to a remote device using the communications interface;
• and
• a battery operable to power the controller and the sensor module.
