Abstract: An aerosol jet printer is used to deposit freestanding quantum dot matrices over optical elements such as LEDs or photodetectors. The printing process avoids the need for photolithographic masks while allowing variation in matrix height to be obtained. The matrices may be assembled with no or little binder material.

Abstract: An aerosol jet printer producing a stream of droplets in a print jet employs direct, droplet-resolving imaging to characterize the statistics of the droplets in flight for improved control of the printed line characteristics.

Abstract: A multi-variable sensor includes a first trace that is configured to measure a first variable and a second trace that is configured to measure a second variable that is different from the first variable. The first trace extends from a first end at a first terminal to a second end at a second terminal and the second trace extends from a third end at the second terminal to a fourth end at a third terminal. The first trace has a first sensitivity to the first variable and the second trace has a second sensitivity to the first variable that is less than the first sensitivity. The second trace has a third sensitivity to the second variable and the first trace has a fourth sensitivity to the second variable that is less than the third sensitivity.
