Gripping Force

This paper presents the design, simulation, fabrication, and testing processes of a new microelectromechanical systems (MEMS) microgripper, which integrates an electrostatic actuator and a capacitive force sensor. One advantage of the presented gripper is that the gripping force and interaction force in two orthogonal directions can be, respectively, detected by a single force sensor. The whole gripper structure consists of the left actuating part and right sensing part. It owns a simple structure and compact footprint. The actuator and sensor are fixed and linearly guided by four leaf flexures, respectively. The left arm of the gripper is driven through a lever amplification mechanism. By this structure, the displacement from the electrostatic actuator is transmitted and enlarged at the gripper tip. The right arm of the gripper is designed to detect the gripping and interaction forces using a capacitive sensor. The MEMS gripper is manufactured by SOIMUMPs process. The performance of the designed gripper is verified by conducting finite element analysis (FEA) simulation and experimental studies. Moreover, the demonstration of biocellulose gripping confirms the feasibility of the developed gripper device.

Exciting Time

Pregnancy is a unique, exciting time in a woman's life, and there are so many changes going on in human body during pregnancy and mouth is no exception , so good oral hygiene is extremely important during pregnancy . Usually oral health is often the most neglected form of health during all stages of life & the most important cause for this neglection is lack of awareness among people & this problems also increases when a lady is pregnant because of mis-perceptions and mis-leading information in the society or due to lack of knowledge. But the fact is during pregnancy many complex physiologic changes occur in the women’s body, which can adversely affect oral health and in turn those oral health problems may lead to pregnancy outcomes like preterm birth or low birth weight. Proper oral care is of utmost importance during pregnancy to avoid these complications. Avoiding foods that may cause oral problems, proper brushing and flossing and having dental consultations on a regular basis are steps to ensure good oral health during pregnancy.

ABSTRACT The idea of intelligent tires is to develop a tire into an active perception component or a force sensor with an embedded microsensor, such as an accelerometer. A tire rolling kinematics model is necessary to link the acceleration measured with the tire body elastic deformation, based on which the tire forces can be identified. Although intelligent tires have attracted wide interest in recent years, a theoretical model for the rolling kinematics of acceleration fields is still lacking. Therefore, this paper focuses on an explicit formulation for the tire rolling kinematics of acceleration, thereby providing a foundation for the force identification algorithms for an accelerometer-based intelligent tire. The Lagrange–Euler method is used to describe the acceleration field and contact deformation of rolling contact structures. Then, the three-axis acceleration vectors can be expressed by coupling rigid body motion and elastic deformation. To obtain an analytical expression of the full tire deformation, a three-dimensional tire ring model is solved with the tire–road deformation as boundary conditions. After parameterizing the ring model for a radial tire, the developed method is applied and validated by comparing the calculated three-axis accelerations with those measured by the accelerometer. Based on the features of acceleration, especially the distinct peak values corresponding to the tire leading and trailing edges, an intelligent tire identification algorithm is established to predict the tire–road contact length and tire vertical load. A simulation and experiments are conducted to verify the accuracy of the estimation algorithm, the results of which demonstrate good agreement. The proposed model provides a solid theoretical foundation for an acceleration-based intelligent tire.

Herbal tooth powders consisting of various ingredients that are available in the market in a wide range. Hence modern methods focusing on these aspects are useful for the standardization of herbs and their formulations. Consumers believed by using herbal-based toothpowders are safe, effective, and less toxic. This study is thus aimed to provide an alternative to the consumer and formulate herbal tooth powder using Clove, Neem Stem, Acacia Stem, Stevia Leaf, Mustard Oil, Salt, Ginger and Amla. The oral cavity infections are the most common types of infections. Dental caries is an infectious disease, causes damage and infection of enamel and dentine. If it is not treated, the infection continues and will lead to tooth loss. The mouth contains normal flora of opportunistic bacteria that are normally non-pathogenic. The imbalance of this situation causes infection and tooth decay. Streptococcus mutants are considered as the main species involved in the development of dental caries. S. mutants, acid-producing bacteria, causes fermentation of carbohydrates which results in tooth decay. Therefore, in the present work, the following aspects of Herbal tooth powders were planned for the formulation, standardization of herbal tooth powder, and anti-bacterial screening of the extracts of herbal tooth powder.
