1. A wearable blast sensor for simultaneously measuring blast pressure of a blast event from multiple directions, comprising:
multiple pressure sensors oriented in individual planes in one multi-directional pressure sensor device for simultaneously measuring blast pressure of the blast event from multiple directions;
at least one blast parameter sensor to measure a blast parameter other than pressure from the blast event;
an analog-to-digital converter having an analog input and a digital output, the analog input coupled to the multiple pressure sensors;
a rolling memory buffer coupled to the digital output of the analog-to-digital converter;
at least one controller coupled to the rolling memory and configured to:
store a time sequence of digital pressure signals from the digital output of the analog-to-digital converter;
write into a blast event memory data from the rolling memory buffer including data corresponding to the blast event if one of the digital pressure signals exceeds a set first threshold;
generate a first blast magnitude indicator signal if any of the digital pressure signals exceeds a second set threshold.
