Apparatus for performing multiple different measurements on a small specimen sample, enabling testing and diagnoses in real time at the point of care are described. The core of the apparatus includes an ultrasonic resonator cavity where acoustic resonances are used to determine the speed of sound and sound attenuation in a single droplet. Acoustic measurements are made in the reflection mode using electrical impedance of a small piezoelectric crystal transducer that operates in the thickness longitudinal mode. Combination of this technology with electromagnetic, electrical, and magnetic fields permits multiple types of measurements to be made using the same resonator cavity.

Various embodiments of an interconnect device and modules and systems that utilize such interconnect device are disclosed. In one or more embodiments, the interconnect device can include a printed circuit board (PCB). The PCB can include a substrate forming a resiliently deflectable element, a conductive material disposed on the substrate, and an electrical contact disposed on the resiliently deflectable element and electrically coupled to the conductive material. The interconnect device can also include a connector that includes a connecting pin configured to electrically couple with the electrical contact of the resiliently deflectable element of the PCB and cause the resiliently deflectable element to deflect when the element contacts the connecting pin.

A fluidic device includes at least one bulk acoustic wave (BAW) resonator structure with a functionalized active region, and at least one first (inlet) port defined through a cover structure arranged over a fluidic passage containing the active region. At least a portion of the at least one inlet port is registered with the active region, permitting fluid to be introduced in a direction orthogonal to a surface of the active region bearing functionalization material. Such arrangement promotes mixing proximate to a BAW resonator structure surface, thereby reducing analyte stratification, increasing analyte binding rate, and reducing measurement time.

A mechanical resonator device. The resonator device includes a resonator element made of an elastic material under tensile stress and adapted for sustaining at least one oscillation mode; and a clamping structure supporting the resonator element. The clamping structure has a phononic density of states exhibiting a bandgap or quasi-bandgap such that elastic waves of at least one polarisation and/or frequency are not allowed to propagate through the clamping structure.
