You need to charge percentage of spend or a flat monthly retainer. Percentage of spend usually means 5-15% of spend with a monthly minimum. 10% of $5,000 per month is $500, so decide how much effort a client is. Could be great or could be a nightmare depending on the expectations and how much effort you need.
Integrated Postsecondary Education Data System. Established: The Integrated Postsecondary Education Data System (IPEDS) is a system of interrelated surveys conducted annually by the National Center for Education Statistics (NCES), a part of the Institute for Education Sciences within the United States Department of Education.
Ionomeric polymer-metal composites (IPMCs) are a class of electroactive polymers (EAPs) that silently bend and exert force in response to an applied voltage. In this work, a unique design is presented where IPMCs are used to accomplish rotary motion.olydimethylsiloxane (PDMS) elastomers are excellent materials for dielectric electroactive polymers (DEAPs) due to their high efficiency and fast response. PDMS suffers, however, from low dielectric permittivity and high voltages are therefore required when the material is used for DEAP actuators.
