| Abstract: | Various technologies described herein pertain to assembling electronic
devices into a microsystem. The electronic devices are disposed in a
solution. Light can be applied to the electronic devices in the solution.
The electronic devices can generate currents responsive to the light
applied to the electronic devices in the solution, and the currents can
cause electrochemical reactions that functionalize regions on surfaces of
the electronic devices. Additionally or alternatively, the light applied
to the electronic devices in the solution can cause the electronic
devices to generate electric fields, which can orient the electronic
devices and/or induce movement of the electronic devices with respect to
a receiving substrate. Further, electrodes on a receiving substrate can
be biased to attract and form connections with the electronic devices
having the functionalized regions on the surfaces. The microsystem can
include the receiving substrate and the electronic devices connected to
the receiving substrate. |
