This paper presents a monolithic, inexpensive, label free, robust pH sensor that can be fabricated in an unmodified CMOS process. The sensor uses a differential p-ISFET architecture which substantially reduces non-ideal common mode effects which corrupt readout in ISFET based pH sensors and occupy only a small footprint. Additionally, the design offers the capability to correct for drift through control of the n-well voltage, which has not been demonstrated previously. We present results obtained from testing the sensor that is fabricated in the AMS 0.35μm process, including a demonstration of the drift correction. We demonstrate a differential sensitivity of 15 mV/pH over the entire pH range, with the ability to remove the already small drift of 0.1 mV/min using the bulk-source voltage adjustment.

Quantum technologies can become enabling for many future applications. In this work, we present concept, modeling and parameter optimization, for a spin-based navigation-grade gyroscope. This technology bridges the gap between high precision optical and MEMS (low cost, small package) gyroscopes. We study a numerical solution taking into account all relevant magnetic fields and back-interactions to provide a better understanding of the transient behavior of the sensor signal and allow for parameter optimization.

Ferroelectrets are piezoelectric polymers, typically cellular polymer foams that exhibit a large piezoelectric response. In this work, we present a biodegradable 3D printed ferroelectret using Fused Deposition Modeling (FDM). Even though the charging process of the ferroelectret is conducted at room temperature, the printed PLA exhibits good charge stability over 150 days at this temperature. A distinctive feature of the manufactured ferroelectret is that its mechanical properties mainly depend on its geometry, offering the possibility for it to be softer than the printed material itself. In fact, the investigated geometry in this paper exhibits a Young’s modulus of 0.5 kPa for stresses under 1 kPa. An excellent piezoelectric coefficient of 600 pC/N was recorded, which is comparable with the well known polypropylene ferroelectret. The presented ferroelectret is suitable for various mechanical sensor application.

The PapillArray tactile sensor is a promising friction-based tactile sensor that uses a pinhole-camera-based transduction principle to sense the movement and forces experienced by soft silicone pillars. In this work, we develop and validate a simulation model of its mechanical and optical behavior. The simulated behavior approximates the response of the physical prototype, with differences explained by manufacturing imprecision. The developed simulation methodology will enable rapid design iteration of future revisions based on this novel optical transduction method, decreasing the design cycle duration and increasing the odds of creating successful hardware sensor prototypes.

This work discusses the peculiar needs of amplitude-gain-control (AGC) loops in oscillators for Lissajous frequency modulated gyroscopes. After comparing possible implementations, a novel dual-mode architecture is disclosed, to simultaneously enable a fast start-up and no relevant distortion of the intended proof mass trajectory. Experimental results on an integrated 50-kHz frequency-modulated gyroscope confirm a start-up time of about 100 ms, with minimized control errors and without any noise worsening.

This paper presents the front-end electronics for beta-cell function monitoring, which will be used for the study and treatment of the type 2 diabetes mellitus. A unique feature of the design is an integrated circuit solution for the Fraction of Plateau Phase (FOPP) detection. The FOPP is the percentage of time when beta-cells, in the islets of Langerhans in the pancreas, show burst activity, which is directly proportional to the extracellular glucose concentration. The proposed integrated FOPP detector circuit adopting a differential envelope detector structure keeps the design overhead to a minimum and only FOPP relevant information is well reserved and processed, resulting in a highly reduced data volume. This allows us to further apply this solution to more advanced invitro and in-vivo beta-cell activity monitoring. The concept is successfully validated by the measurement results of an application specific integrated circuit (ASIC) in XFAB XH018 CMOS process.

Smart textiles have been attracting considerable interest in imparting a wide range of functions to traditional clothing ranging from sensing, actuation, data processing, and energy storage. In the case of textile-based strain sensors, most of the studies proved that they can work in principle, however, producing strain sensors with desirable properties such as stable sensitivity, small hysteresis, large enough working range, and good repeatability still remains a challenge necessitating the developments of novel technologies for soft sensors. This paper conducts a systematic approach to investigate the electromechanical properties of the knitted strain sensors to find out the optimum process parameters. We found a repeatable and robust method to produce knitted strain sensors with low hysteresis at a working range of at least 40%.

This work presents a novel organic microwave resonator (OMR) humidity sensor fabricated by casting the electrically conducting polymer PEDOT:PSS on a flexible cellulose nanofibrils (CNF) film. The CNF substrate functioned as a functional sensing component to impart the microwave resonator superior sensing performance to humidity. The measured transmission coefficient (S21) of the OMR showed a resonant frequency at 2.78 GHz and a resonant amplitude of 14.95 dB. Higher relative humidity levels (from 0 to 90%) downshifted the S21 amplitude and increased the quality factor of the device. The sensor operated based on simultaneous adsorption of moisture in the CNF film and interactions between water molecules and PEDOT:PSS. The devised sensor further demonstrates the promise of organic microwave devices for next-generation flexible chemical sensors.

Current sensor arrays require multiple sensing films with partial selectivities. However, preparation of multiple number of sensing films is cumbersome. Novel sensing materials such as polyaniline doped with atomic gold are favoured candidates for sensing films due to "tunable" electrocatalytic activity. This paper explores a sensor configuration of polyaniline-platinum electrodes decorated with bi-atomic gold electrocatalyst and ionic liquid as electrolyte. Electrocatalytic activity of the modified nanocomposite towards electrooxidation of alcohols is confirmed. For real-time application, suitable choice of reference electrode operational in ionic liquid electrolyte is suggested.

Autonomy and minimal disruption are key desirable features for sensors to be deployed in medical, industrial, vehicle and infrastructure monitoring systems. Using a passive structure to transduce the quantity of interest into an acoustic or electromagnetic wave could offer an attractive solution for remote sensing, lifting the requirements of installing active materials, electronics, and power sources in remote, inaccessible, sensitive, or harsh environment locations. Here, we report a simple cavity and ball structure that transduces fluid flow through a pipe into an acoustic signal. A microphone on the outside wall of the pipe records the intensity and arrival rate of the sound pulses generated by collisions between the ball and the cavity walls. Using this approach external measurement of flow is demonstrated with adequate repeatability before any acoustic signal processing. This result is expected to open the way to the implementation of passive, remotely readable sensors for fluid flow and other fluid properties of interest.
