Gel instrumental in 3D bioprinting biological tissues — ScienceDaily The eventual creation of replacement biological parts requires fully three-dimensional capabilities that two-dimensional and three-dimensional thin-film bioprinting cannot supply. Now, using a yiel… Earphone tracks facial expressions, even with a face mask — ScienceDaily researchers have invented an earphone that can continuously track full facial expressions by observing the contour of the cheeks — and can then translate expressions into emojis or silent speech c… Cameras that can learn what they are viewing — ScienceDaily The research suggests a future with intelligent dedicated AI cameras — visual systems that can simply send high-level information to the rest of the system, such as the type of object or event tak… Ice Age footprints tell incredible story of mother and child’s journey Tracks left by a small child also appear alongside the main tracks at different points, as though the person carrying them stopped to put them down every now and then. From their size, the child wa… Gait-analyzing wearable sensors could save users a visit to the clinic inertial measurement unit (IMU), which combines an accelerometer and a gyroscope. In most cases, though, such setups are limited to providing data on acceleration, and the rate at which the feet ro… Wearable sensors can be printed directly onto skin at room temperature Flexible electronics have opened up some interesting possibilities when it comes to wearable sensors that can be applied to the skin, taking the form of tattoo-like films and sleeves that monitor v… What tiny surfing robots teach us about surface tension — ScienceDaily Propelled by chemical changes in surface tension, microrobots surfing across fluid interfaces lead researchers to new ideas. water striders — long-legged insects that dimple the surface of the wa…
