The Merkel cell expresses the PIEZO2 mechanosensitive ion channels; mechanical activation of the channel causes depolarisation of the Merkel cell and consequent release of [1] serotonin into a synapse with the associated nerve ending, to also depolarise the later. [3] The nerve ending meanwhile expresses an unknown mechanosensitive channel. [1]
Merkel cells, also known as Merkel–Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates. They are abundant in highly sensitive skin like that of the fingertips in humans , and make synaptic contacts with somatosensory afferent nerve fibers .

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.
A linear actuator opens and closes valves that can be operated via linear force, the type sometimes called a "rising stem" valve. These types of valves include globe valves, rising stem ball valves, control valves and gate valves. [2] The two main types of linear actuators are diaphragm and piston.
Tactile haptic feedback is common in cellular devices. In most cases, this takes the form of vibration response to touch. In most cases, this takes the form of vibration response to touch. Alpine Electronics uses a haptic feedback technology named PulseTouch on many of their touch-screen car navigation and stereo units. [ 65 ]
Control your cough. Coughing is a physiologic way to rid one of some of the congestion, says Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security. Controlled cough ...
Proportional control is a type of linear feedback control system in which a correction is applied to the controlled variable which is proportional to the difference between the desired value (SP) and the measured value (PV). Two classic mechanical examples are the toilet bowl float proportioning valve and the fly-ball governor.
