Microchannel particle deposition (MPD) is a wafer-scale thick-film deposition process used to accurately and in a scalable way deposit nanoparticles. Unique features include: 1) full wafers patterning in 15-minutes, 2) structures can be deposited with a size ranging from 1 – 50 microns and with high aspect ratios up to 5 and 3) full 3D-control of the printed structures. In addition, I can share some of the applications we’re focusing on such as: 1) printing sensing electrodes for metal oxide gas sensors, 2) printing of getters for microbolometers and 3) printing of porous electrodes for biosensing applications.

Metal oxide gas sensor example: Traditionally, sensing elements of metal oxide gas sensors are fabricated using drop-casting. Our MPD process is used as a superior alternative to fabricate these MOX sensors as its 10x more scalable, further reduces the form factor and lowers the power consumption by 5x. In addition, our MPD technology allows for the deposition of sensing element arrays, which enables detection of environmental gasses for safety, wildfire detection, methane detection, NOx/greenhouse gases.
