A pressure measurement system includes a pressure pod with two chambers separated by a diaphragm such that a deformation/movement of the diaphragm is indicative of a difference between the pressures of the two chambers. Such deformation/movement is detected by a device that has no physical contact with the diaphragm, for example, by an optical detector that detects a change in the shape of the diaphragm or a movement of a protrusion on the diaphragm.

The invention relates to a device (2) for collecting a breath sample from a user and containing target compounds intended to be characterized by an analysis device (3), comprising: a piece (10) for collecting the breath sample comprising a first tab (15) referred to as the compression tab; and a sampling tube (4), intended to be connected to the analysis device (3), passing through an inner pipe (13) of the piece (10), and extending along the longitudinal axis away from and opposite the compression tab (15).

A highly integrated analyte detection device is provided. The transmitter is composed of a shell, a cover body, a circuit module and an electrical connection module. The circuit module is fixedly connected with the shell, one end of the electric connection module is fixedly connected with the circuit module, the other end extends to the outside through the through hole on the shell, and is electrically connected with other structural parts. The sealing material is filled between the electric connection module and the through hole, and the cover body and the shell are clamped together to form a seal for the circuit module, which makes the transmitter structure simpler. The shell and the circuit module can be processed separately and then assembled. The production process is less difficult and the production cost is reduced at the same time.

A probe device provides an enhanced bioelectric and spring-loaded sensing tip with an integrated force sensor. The probe device measures the bioelectric conductance value from a patient for therapeutic and/or diagnostic purpose using the spring-loaded sensing tip. In addition, the probe device measures the force applied by the spring-loaded sensing tip against the patient using the integrated force sensor. Using feedback from the force sensor and the bioconductive data of the patient, the force applied at the spring-loaded sensing tip may be adjusted to obtain improved results.

An in-ear optical sensor device sits deep within the ear canal of a subject such that is in the cartilaginous region and/or the bony region of the ear canal where effects from temporomandibular joint activity or other movement, and external light, are limited. The device has a lateral housing and a medial articulating head joined at an articulation joint so that the medial articulating head may be angled relative to the lateral housing to help the device fit within tortuous ear canals. The device also includes a seal configured to conform to the shape of the ear canal to physically support the device to further limit movement and block environmental light. An audio receiver is also included in the device.

Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

A polymer holder for a biosignal processing device, wherein a wall of the polymer holder forms a pocket, and the wall follows an outer contour of the biosignal processing device. The polymer holder has a first aperture for inserting the biosignal processing device into the pocket and removing the biosignal processing device from the pocket. The polymer holder includes an electrically conductive contact structure, which is in a wired electric contact with electrodes that receive the at least one biosignal, at a rear section opposite to the first aperture, and the electrically conductive contact structure is at least partly attached inside the wall. The electrically conductive contact structure is electrically connected with a counterpart of the biosignal processing device in response to an insert of the biosignal processing device in the pocket.

The present invention provides a measuring method for prolonging a usage lifetime of a micro biosensor implanted subcutaneously to measure a physiological signal associated with an analyte. The micro biosensor includes a working electrode and a counter electrode, wherein the counter electrode includes silver and a silver halide having an initial amount. The method includes cyclic steps of: applying a measurement voltage to drive the working electrode to measure the physiological signal, where the silver halide is consumed by a specific amount; stopping applying the measurement voltage; and whenever the physiological parameter is obtained, applying a replenishment voltage to drive the counter electrode, thereby the silver halide of a replenishment amount being replenished to the counter electrode, wherein a guarding value of a sum of the replenishment amount and the initial amount subtracting the consumption amount is controlled within a range of the initial amount plus or minus a specific value.
