Chiral sensors

open access: yesTrAC Trends in Analytical Chemistry, 2019
Chirality has a crucial effect on clinical, chemical and biological research since most bioactive substances possess chirality in the natural world. Thus, new effective methods and/or (nano)materials are required to explain chiral recognition of chiral substances, which always become a hot topic in pharmaceutical and chemo/biological study.

Equivalent Circuit Model of an Optomechanical MEMS Electric Field Strength Sensor

open access: yesProceedings, 2018
We present a simple equivalent circuit model for the transfer function of an optomechanical MEMS transducer capable of distortion-free electric field strength measurements. This model allows not only to qualitatively understand the characteristics of the

Sensory capacity: an information theoretical measure of the performance of a sensor

open access: yes, 2016
For a general sensory system following an external stochastic signal, we introduce the sensory capacity. This quantity characterizes the performance of a sensor: sensory capacity is maximal if the instantaneous state of the sensor has as much information
