Description
MicroStrain, Inc. announces the availability of the miniature EmbedSense™
wireless sensor. EmbedSense™ is a tiny wireless sensor and data acquisition
system that is small enough to be embedded in a product, enabling the creation of
smart structures, smart materials and smart machines.
EmbedSense™ nodes can be placed within implants, on spinning machinery and
within composite materials. Because they can tolerate extreme G levels and high
temperatures, sensor measurements can be made in applications where previously no
data could be obtained.
Batteries are completely eliminated which means that the embedded sensors and EmbedSense™
node can be queried for the life of the structure. EmbedSense™ uses an inductive
link to receive power from an external coil and to return digital strain, temperature
and unique ID information.
Applications range from monitoring the healing of the spine, to testing strains
and temperatures on jet turbine engines.
EmbedSense™ tags can read data from multiple types of sensors, including semiconductor
temperature sensors, thermocouples, strain gauges, pressure sensors, and load cells.
