Artificial muscle for soft robotics: Low voltage, high hopes

soft robotics

soft robotics

Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.

3-D printing aids in understanding food enjoyment

3-D printing aids in understanding food enjoyment

Tasting food relies on food volatiles moving from the back of the mouth to the nasal cavity, but researchers have wondered why airflow doesn’t carry them in the other direction, into the lungs. Now a team of engineers, using a 3D printed model of the human airway from nostril to trachea, has determined that the shape of the airway preferentially transfers volatiles to the nasal cavity and allows humans to enjoy the smell of good food.

Study finds metal foams capable of shielding X-rays, gamma rays, neutron radiation

metal foam

Research from North Carolina State University shows that lightweight composite metal foams — like the one pictured here — are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.
