The detector is capable of spatial positioning of ion beams with sub nA current intensity, high linearity, large dynamic range and dark current noise <10 pA. Each channel is connected to its own calibrated amplifier for true simultaneous integration. To demonstrate the detector capability, 2-dimensional ion images are presented for ions emitted from a desorption atmospheric pressure chemical ionisation source with peak ion current of ∼30pA. The novel detection system facilitates the characterization and optimization of ambient ionisation sources in terms of electrical and geometric conditions for improved ion generation and coupling with a mass spectrometer.","PeriodicalId":92164,"journal":{"name":"2017 IEEE Sensors Applications Symposium (SAS).

In this regard, tactile e-skin is needed for accurate haptic perception in robots, amputees, as well as, wearable electronics. For example, a flexible e-skin provided with touch/pressure sensors will allow robots to detect the strength and location of the pressure exerted on the skin surface by surrounding objects. Energy autonomy, or also called self-powering, is also a critical feature for an e-skin, enabling portability and longer operation times without human intervention. Further, making the e-skin transparent adds an extra dimension in the functional design space of e-skin, allowing the integration of a solar cell underneath the skin while preserving light energy harvesting. Recent advances in photovoltaics are oriented towards the development of solar cells on stretchable/flexible substrates which will benefit the realization of suggested self-powered technology. Accordingly, the novel approach presented in this demo consists in a vertical layered stack structure, comprising a solar cell attached to the back plane of a transparent tactile skin, where e-skin transparency being a crucial feature that allows light pass through, making the building-block unique, and opening a new promising line of energy autonomous devices for portable flexible electronics.","PeriodicalId":92164,"journal":{"name":"2017 IEEE Sensors Applications Symposium (SAS).

In present study, a nanocomposite imprinted LSPR sensor was developed for determination of cis-jasmone vapors. Molecular imprinted sol-gels (MISG) were fabricated on the surface of Au nano-islands via spinning coating. For enhancing the sensitives of sensors, AuNPs was sputtered on the MISG layers. The sensitives and selectivelies of samples recoated divers thickness of AuNPs were compared and discussed. The result indicated that the sensitivity of AuNPs/MISG/AuNPs was higher than that of AuNPs/MISG. In addition, AuNPs/MISG coated with 3 nm AuNPs shown a better sensitive and selectively. In-situ response was verified to be fast, selective and reversible. The absorbance spectra of cis-jasmone vapors linearly increased with its concentration in the range of 10 to 75 ppm, with the limit of detection of 3.45 ppm (S/N=3).

At the transmitter, a combination of a pulse width modulation (PWM) signal and a redundant run-length limited encoded on-off keying (OOK) signal is used for data transmission. The LED receiver uses OOK and the OFF periods therein for VLC reception. The range of such a system is however affected by ambient light changes and device portability. To address this problem, we propose a two-step decoder with edge detection followed by K-means clustering and adaptive threshold detection. We show that the proposed system achieves about 33% higher range in comparison to a non-adaptive VLC system.","PeriodicalId":92164,"journal":{"name":"2017 IEEE Sensors Applications Symposium (SAS).

In this paper, we propose a small-sized 6-axis F/T sensor with a novel arrangement of 12 transducers using the force transducer we have previously developed. The copper beryllium used in our sensor reduces hysteresis in each transducer. Additionally, the sensor provides digital output via I2C bus to reduce the susceptibility to noise, and reduce the number of required wires. Sensor characteristics such as its sensitivity, signal-to-noise ratio, linearity, and hysteresis are determined. More importantly, we showed that our sensor can detect and measure the 6-axis F/T.","PeriodicalId":92164,"journal":{"name":"2017 IEEE Sensors Applications Symposium (SAS).
