in a robot, connecting
living muscle actuators to
the robot, helping it to
walk, jump, or swim.
Researchers also introduced
a unique printable
ink that allowed, for
the first time, the digital
printing of multi-layer
stretchable circuits, electronic
skins (e-skins),
and adhesive medical
patches for electrophysiological
monitoring. The
materials and methods
enable the scalable fabrication
of stretchable circuits
using simple extrusion
printers. These elec -
trical circuits can be
printed on a medical
adhesive for patient biomonitoring,
over elastic
polymer to make artificial
skin for robotics ap -
plications, and onto textiles
for wearable com -
puting.
A novel approach to COVID-19 vaccination is a low-dose, inexpensive,
hybrid microneedle array (Hybrid-MNA) that allows for a
very small amount of a vaccine to elicit strong and long-lasting
immunity against SARS-CoV-2 infections. This can significantly
help reduce vaccine shortages.
ergy and the environment, product
design, and robotics. Researchers are
using new techniques to 3D-print ce -
ramics, lithium-ion battery electrodes,
and devices for aerospace and biomedical
industries.
Bioengineering work includes ex -
ploring myosin protein for synthetic
muscle, using DNA origami for
nanomechanics of multiprotein systems,
developing ro botic interfaces for
microsurgery, and making bio-inspired
robots. They pair wearable medical
devices with advanced analytics and
machine learning to personalize rehabilitation
for joint injuries and
pathologies.
CMU uses techniques from tissue
engineering to refine tendon-like collagen
threads for a new generation of
robots. The goal of this research was to
better understand how to make an artificial
tendon for use on a robot. In our
bodies, tendons work to connect muscle
to bone and are rather strong. This
means that these collagen threads
could be used for a very similar purpose

Collaborators led by
CMU are developing a
novel approach to ad -
ministering COVID-19
inoculations that ad -
dresses both immunological effectiveness
and manufacturing efficiency with
a low-dose, inexpensive, hybrid
microneedle array (Hybrid-MNA) technology.
The intradermal delivery device
builds on more than a decade of work
on microneedle array technology. The
novel vaccine delivery method allows
for a very small amount - potentially
1/100th of the dose of a traditional vaccine
- to elicit strong and long-lasting
immunity against SARS-CoV-2 infections.
This can significantly help
reduce vaccine shortages.
