Detection of formaldehyde vapor using mercaptophenol-coated piezoresistive cantilevers

Sensors and Actuators B: Chemical, 2007
Piezoresistive cantilevers coated with mercaptophenol self-assembled monolayers were used to detect formaldehyde vapor at room temperature. The three isomers of mercaptophenol, namely 2-, 3-, and 4-mercaptophenol, were tested as probe molecules.

Piezoresistive cantilever platform for label-free detection of molecules

2014 IEEE 5th Latin American Symposium on Circuits and Systems, 2014
MEMS sensors can be used for label-free detection in many different biological studies. Usually in this procedure the presence of special substance in a sample can be monitored based on its interaction and binding with specific probe molecules which are immobilized on a sensor.

Ethanol vapor detection in saline solution using piezoresistive microcantilevers

Review of Scientific Instruments, 2006
We report detection of ethanol in a phosphate buffered saline (PBS) solution using a low-power piezoresistive microcantilever-based system that has the potential to be used in the human body. PBS was used to simulate interstitial fluid and a permeable hydrophobic membrane was employed to transport ethanol vapor to the sensor while blocking the liquid ...

Multiscale Heterogeneities-Based Piezoresistive Interfaces with Ultralow Detection Limitation and Adaptively Switchable Pressure Detectability

ACS Nano
Mechanical compliance and electrical enhancement are crucial for pressure sensors to promote performances when perceiving external stimuli. Here we propose a bioinspired multiscale heterogeneity-based interface to adaptively regulate its structure layout and switch to desirable piezoresistive behaviors with ultralow detection limitation.

Magneto-piezoresistive microstructured composites for detecting magnetizing field direction

2015
Magnetorheological composites made of iron micro-particles dispersed, near the percolation threshold in an elastomeric polymer, exhibit the concomitant effects of piezoresistivity and elastomagnetism, and their optimization can be obtained by a proper combination of the particle size, shape, volume fraction, magnetic permeability and electrical ...
