TL;DR: In this paper, a silicon-based three-axial force sensor is used in a flexible smart interface for biomechanical measurements, which combines responses from four piezoresistors obtained by ion implantation in a high aspect-ratio cross-shape flexible element equipped with a 525 m high silicon mesa.

TL;DR: A microcontroller-based multichannel telemetry system, suitable for in vivo monitoring of physiological parameters, that provides good flexibility and interesting performance, such as the threshold monitoring, the transmission error detection, and a low power consumption, thanks to the implementation of a sleep mode.

TL;DR: In this paper, a proportional valve for the control of the outlet pressure of a fluid flowing therethrough comprising a valve body (1) with an inlet port (15) and an outlet port (17) for the fluid and an inner chamber, within which there is formed a valve seat (9) whose opening is varied by means of a shutter (10) axially movable from and towards the valve seat, the movement of the shutter being controlled by a SMA actuating member acting antagonistically to elastic means (12), the temperature of the fluid being lower than the transition

TL;DR: A different approach to locomotion has been developed based on "sliding clampers", which has been implemented in a minirobot system and has demonstrated (both theoretically and experimentally) to be effective in reducing the "accordion effect".

TL;DR: In this article, an intracorporeal probe is designed for examining hollow organs or natural or artificially created body cavities in the human or animal body, the probe (10) being designed in the form of a capsule that can be introduced into the body without external connecting elements, comprising an elongate housing (16) and an image pickup unit (26) inside the housing.
