A hybrid MEMS microfluidic gyroscope is disclosed. The hybrid MEMS microfluidic gyroscope may include a micro-machined base enclosure having a top fluid enclosure, a fluid sensing enclosure and a bottom fluid enclosure. The hybrid MEMS microfluidic gyroscope may include a plurality of cantilevers disposed within the bottom semi-circular portion of the micro-machined base enclosure or a single membrane disposed within the bottom semi-circular portion of the micro-machined base enclosure.

A method for preparing a fully soft self-powered vibration sensor mainly uses a laser carbonization technology to prepare a two-dimensional porous carbon electrode with an origami structure, and then transfers the two-dimensional porous carbon electrode to a three-dimensional polydimethylsiloxane (PDMS) cavity through mold transfer; Finally, a laser engraving technology is used to create microstructures on surfaces of the porous carbon electrode and a PDMS film. The sensor includes the PDMS film, a liquid metal droplet oscillator, a porous out-of-plane carbon electrode, and a 3D PDMS cavity assembled tightly from top to bottom. The sensor works based on the triboelectric nanogenerator principle, when the sensor is excited by vibrations, contact and triboelectrification at an interface of the liquid metal droplet oscillator and PDMS film charge both objects, making contact surfaces carry stable charges, which allows the movement of the liquid metal droplet oscillator to output current through electrostatic induction.

Systems and methods relating to sensors for measuring acceleration. Two attached containers are each filled with different liquids. At each junction of the two liquids, an indicator is placed. When acceleration forces are applied to the sensor, the indicator moves when the boundary between the two liquids similarly move. The amount of movement of the boundary and of the indicator is proportional to the amount of acceleration for applied. A tracking subsystem tracks the position of the indicator and, by determining the amount of movement of the indicator, the amount of acceleration force applied can be calculated. The indicator can be a particle or it can be a beam-like element that deflects when the boundary between the two liquids move.

Disclosed are a motion-sensitive field effect transistor (MSFET), a motion detection system, and a method. The MSFET includes a gate structure with a reservoir containing conductive fluid and gate electrode(s). Given position(s) of the gate electrode(s) and a fill level of the fluid within the reservoir, contact between the gate electrode(s) and the fluid depends upon the orientation the MSFET channel region relative to the top surface of the conductive fluid and the orientation of the MSFET channel region relative to the top surface of the conductive fluid depends upon position in space and/or movement of the MSFET and, particularly, position in space and/or movement of the chip on which the MSFET is formed. An electrical property of the MSFET in response to specific bias conditions varies depending on whether or not or to what extent the gate electrode(s) contact the fluid and is, thus, measurable for sensing chip motion.

Impact or acceleration sensor, which contains a liquid droplet and is designed such that the position and/or distribution of the liquid indicates whether an impact or any other acceleration of a predetermined minimum magnitude has occurred, includes: first and second foils, a cavity disposed between the foil faces of the foils and at least one retaining structure disposed on the foil face of the first and/or second foil and functions to maintain the liquid in a predetermined first sub-volume of the cavity. The retaining structure is a region of the first and/or second foil formed as a local elevation, depression or irregularity of the foil face, which forms a passable barrier for the wetting and/or contacting of the first and/or second foil by the liquid and defines an area piece of the foil face of the first and/or second foil corresponding to the first sub-volume.

The disclosure discloses an acceleration sensor, where the acceleration sensor comprises: a housing, and a mass block in the housing and connected with the housing via at least two hanging beams, where an auxiliary buffer component is further provided between the mass block and a bottom surface of the housing, and an elastic coefficient of the auxiliary buffer component decreases as force applied thereon increases.

A device includes a channel, a slit, and a cap. The channel is formed on a surface of the device. The slit separates the channel to a first portion and a second portion. The first portion comprises liquid metal, e.g., gallatin. The second portion comprises gas. The liquid metal moves within the channel between the first and the second portions in response to external stimuli, e.g., pressure. The liquid metal moving within the channel changes electrical characteristics, e.g., capacitive value, inductance value, resistance value, resonance frequency, etc., of the device.
