Owing to the technology growth, especially in Microsystems technology and Nanotechnology, new products will provide new ways to sense variables that are crucial for product improvement and system reliability. A big concern of the scientific community is the measurement of low level flow measurements, especially for the biomedical and/or systems on a chip approaches.Design/methodology/approach – A new flow meter concept design consists of a surface micromachined sensor having an optical high reflective mirror made of gold, which is attached to unique cantilever designs that bend due to the drag force of mass flow. The bending of the cantilevers produces the mirror to approach/depart from an optical fiber end‐tip. The reflective light to fiber is modulated using a Fabry‐Perot interferometry technique to determine the mirror separation to the fiber, which corresponds to the mass flow.Findings – The new concept design shows a big potential approach to measure low flow measurements for air, gas and liquids of low viscosity. The results of this concept, through finite element analysis, show that the material used to build the sensor, makes them excellent candidates for fabrication. The stresses of the materials and allowable (readable) bending are among the tolerances of such materials/construction‐design. The sensor is not affected by electromagnetic interference and does not require electrical currents to sense, i.e. it is perfectly suited for biomedical and low mass‐flow sensing such as lab‐on‐chip applications.Originality/value – Among all approaches to sense low flow measurements, most of them need either “big” turbine approaches (dimensions over 1 cm diameter), or the need of an electrical approach needed in the end measurement sensor. This work proposes a non‐electrical approach.

This study examines the conditions that lead to workplace violations for low-wage immigrant workers, and how family life shapes their decision to speak up. I also highlight how both employer abuse and the claimsmaking process can impact individuals and their families.
This research adopts a mixed-method approach that includes a survey of 453 low-wage workers seeking pro bono legal assistance and 115 follow-up interviews with claimants. I also conduct a five-year ethnography of both a monthly state workshop provided for injured workers and a pro bono legal aid clinic in a predominantly Latino agricultural community on the California central coast.
Beyond the material effects of lost income, the stress of fighting for justice can have negative emotional impacts that intersect with complex family dynamics. While families can be an important source of support and inspiration during this time, the burden of the breadwinner can also temper workers’ willingness to engage the labor standards enforcement system. Transnational obligations can further introduce a demobilizing dual frame of reference for workers who often hide their abuse from family members abroad who depend on them.
Workplace abuse and the actual process of legal mobilization can have far-reaching effects on the families of low-wage immigrant workers, suggesting the need for a more holistic understanding of the claimsmaking experience.
This chapter tracks the challenges that workers face even once they have come forward to fight for their rights, and the multiple effects on families and children.

Possibly one of the greatest misconceptions about Chicano historiography is the view that published intellectual writings by Chicanos are of recent vintage, traceable only over several decades. This assumption is in part supported by the large and growing body of contemporary published materials by and about Chicanos, especially within the past 15 years.
