Folch has written a total of six books, comprising two general science books in Catalan (translated titles:
Caught on the Internet and
The Science in Soccer), a textbook in English (
Introduction to BioMEMS), a book about soccer in English (
For the Love of the Ball), a microfluidics book in English (
Hidden In Plain Sight - The History, Science, and Engineering of Microfluidic Technology), and a general-public microfluidics book also in English (
How the World Flows - Microfluidics from Raindrops to Covid Tests)
. •
Caught on the Internet (Editorial Empuries, 1997) teaches what the Internet is about to computer-illiterate audiences, starting from bits and bytes and ending with issues such as social fairness and hackers. This book is in its second edition and an extract of it is used in a textbook for Catalan middle schoolers. •
The Science in Soccer (Editorial Empuries, 2004) uses soccer examples to convey science. The book is organized in chapters related to various soccer subjects ("The ball", "The field", "The player", etc.). Inside each chapter we find the answers to questions such as what it would be like to play soccer in each of the planets of the Solar System, why the ball is more than one meter ahead of where we think it really is in a 100 km/h kick (due to delays in the transmission of the nervous impulse), or why soccer balls are made of 12 pentagons and 20 hexagons, etc. Folch has used examples from this book to give outreach lectures to high-schools, middle-schools and elementary schools. •
Introduction to BioMEMS (CRC Press, 2012) covers the whole breadth of
Bio-MEMS (Biomedical MicroElectroMechanicalSystems), including classical microfabrication, microfluidics, tissue engineering, cell-based and non-cell-based devices, and implantable systems. This textbook has now been adopted worldwide (~100 departments in 18 countries). •
For the Love of the Ball (Amazon, 2013) tells the history and methods of FC Barcelona's youth academy. Folch kept a related blog site during 2014-2017, titled
La Ciencia del Fútbol, where he talked about FC Barcelona's state of affairs with a scientific perspective. •
Hidden In Plain Sight (MIT Press, 2022) describes the development and use of key microfluidic devices, explaining not only the technology but also the efforts, teams, places, and circumstances that enabled these inventions. •
How the World Flows (Oxford University Press, 2025) acts like a microscope that pulls the reader into the barely noticeable, Lilliputian world of fluids at small scales--the microfluidic world-and answers the question "What is microfluidics?" in non-technical language. Folch also created a large Catalan Poetry Selection. This webpage, originally hosted by M.I.T. and manually typed in 1995 just one year after the World Wide Web started, was, at the time, the first online literary resource of its kind and size in any language. Still widely visited, the selection features 800 poems and 176 Catalan poets spanning ten centuries, including 24 unpublished poets. ==Media coverage==
