SICK Inc., a global provider of sensor technology, broke ground Wednesday on a $64 million expansion in Bloomington.

Based on this ionogel, they have developed iontronic pressure sensor arrays with humidity-insensitivity and broad linear response range.

Sensor arrays are normally made from state-of-the-art materials like HgCdTe or InAs/GaSb superlattices, with high quantum efficiency in short-, mid-, and long-wave infrared bands.
