We report the electronic recording of the touch contact and pressure using an active matrix pressure sensor array made of transparent zinc oxide thin-film transistors and tactile feedback display using an array of diaphragm actuators made of an interpenetrating polymer elastomer network. Digital replay, editing and manipulation of the recorded touch events were demonstrated with both spatial and temporal resolutions. Analog reproduction of the force is also shown possible using the polymer actuators, despite of the high driving voltage. The ability to record, store, edit, and replay touch information adds an additional dimension to digital technologies and extends the capabilities of modern information exchange with the potential to revolutionize physical learning, social networking, e-commerce, robotics, gaming, medical and military applications.

Proximity and tactile multiresponse sensing electronic skin enriches the perception dimension, which is of great significance in promoting the intelligence of electronic skin. However, achieving real-time visualization in sensors such as proximity and tactile feedback remains a challenge. A proximity and tactile sensor with visual function is designed, which can realize optical early warning and electrical recognition when the object is near, and optical display and electrical output when the object is in contact.

Sensory feedback is crucial for motor control as it establishes the internal representation of motion. This study investigates changes in sensory feedback in hemiparetic stroke by analyzing the laterality index (LI) of somatosensory evoked potentials (SEPs) during movements of the paretic arm, focusing on a shift from the lesioned to the contralesional hemisphere. Three chronic stroke participants performed isometric lifts of their paretic arms at two different levels of their maximum voluntary contraction while receiving tactile finger stimulation.

Tactile sensation and recognition in the human brain are indispensable for interaction between the human body and the surrounding environment. It is quite significant for intelligent robots to simulate human perception and decision-making functions in a more human-like way to perform complex tasks. A combination of tactile piezoelectric sensors with neuromorphic transistors provides an alternative way to achieve perception and cognition functions for intelligent robots in human-machine interaction scenarios.

Background: The pelvis is one of the most common areas for metastatic bone disease. We recently described the use of a minimally invasive percutaneous screw fixation of metastatic non-periacetabular pelvic lesions, with excellent results.
Description: The procedure can be completed in a standard operating theater without the need for special instruments.
