Face masks smarten up

A conformable sensor interface that can be attached to the inside of a face mask can be used to monitor breathing patterns, skin temperature, verbal activity and the fit of the mask itself. The photograph on the cover shows the sensor interface, which incorporates a gecko-inspired thin adhesive layer that allows it to be repeatedly attached and detached from different commercial face masks.

Research Briefings

  • An organic artificial spiking neuron based on nonlinear ionoelectronic phenomena is reported that is sensitive to ionic and biomolecular species common in neuronal signalling. The neuron realistically emulates the function and firing properties of biological neurons and enables biohybrid interfaces made of artificial and biological components that function in real time.
