Non-electric touchpad takes sensor technology to extreme conditions

Researchers have developed the world's first soft touchpad that can sense the force, area and location of contact without electricity. The device utilizes pneumatic channels, enabling its use in environments such as MRI machines and other conditions that are unsuitable for electronic devices. Soft devices like soft robots and rehabilitation aids could also benefit from this new technology.

New method of flexing on electronics

If a phone or other electronic device was made of soft materials, how would that change its use? Would it be more durable? If hospital health monitoring equipment was made of less rigid components, would it make it easier for patients to wear? While electronics of that type may still be far in the future, researchers have developed an innovative method for constructing the soft electronic components that make them up.

A new hydrogel semiconductor represents a breakthrough for tissue-interfaced bioelectronics

The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself--in short, a hydrogel. Semiconductors, the key materials for bioelectronics such as pacemakers, biosensors, and drug delivery devices, on the other hand, are rigid, brittle, and water-hating, impossible to dissolve in the way hydrogels have traditionally been built. Scientists have now solved this challenge that has long stymied researchers, reimagining the process of creating hydrogels to build a powerful semiconductor in hydrogel form. The result is a bluish gel that flutters like a sea jelly in water but retains the immense semiconductive ability needed to transmit information between living tissue and machine.

New diamond bonding technique a breakthrough for quantum devices

A paper has solved a major hurdle facing researchers working with diamond by creating a novel way of bonding diamonds directly to materials that integrate easily with either quantum or conventional electronics. With this technique, the team directly bonded diamond with materials including silicon, fused silica, sapphire, thermal oxide, and lithium niobate without an intermediary substance to act as 'glue.' Instead of the several-hundred microns thick bulk diamonds typically used to study quantum qubits, the team bonded crystalline membranes as thin as 100 nanometers while still maintaining a spin coherence suitable for advanced quantum applications.
