Piezoelectric Materials create electrical charge when mechanically stressed. Natural materials with this property are quartz, human skin, and human bone. In medical field this material is used as medical sensors and low power medical devices. The material is specifically formulated with high coupling values and high dielectric properties and is well suited for thin and small parts. Applications include sensors for catheters, blood pressure, auditory sounds, vascular flow, and medical imaging. Depending on the design of a sensor, different 'modes' to load the piezoelectric element can be used: longitudinal, transversal and shear. Detection of pressure variations in the form of sound is the most common sensor application. Piezoelectric microphones (sound waves bend the piezoelectric material, creating a changing voltage) and piezoelectric pickups for electrically amplified guitars. A piezo sensor attached to the body of an instrument is known as a contact microphone.Piezoelectric sensors especially are used with high frequency sound in ultrasonic transducers for medical imaging and also for industrial nondestructive testing.

The short pulse laser systems are used to treat pigmented lesions including freckles and birthmarks, congenital melanocytic naive, blue naive, naive of Ota/Ito and Becker naive. It effectively treat the lesions by confining their energy to the melanosomes, which are the tiny granules containing melanin inside the pigment cells. The results of laser treatment depend on the depth of the melanin and the colour of the lesion and are to some degree unpredictable. The superficially located pigment is treated with shorter wavelength lasers while removal of deeper pigment requires longer wavelength lasers that penetrate to greater tissue depths.

Pigtail catheter is an angiographic catheter with a tightly curled end to reduce the impact of the injectant on the vessel wall or to remain in a chamber or space for drainage.

Pigtail diagnostic catheter is used to cannulate the contra lateral common iliac artery over the aortic bifurcation. It is placed at the apex of the left kidney for ideal imaging. Because the right kidney is usually lower than the left kidney, placement of the pigtail catheter at the top of the left kidney facilitates the visualization of bilateral kidneys and their respective blood supplies.

Pill crusher is a device used to crush pills. It crushes pills and tablets into powder to make medication administration easier for individuals who have difficulty in swallowing whole pills. It protects nurses from strain injury, eliminates noise & the need for cleaning, and all cross-contamination. It also reduces the use of liquids as the fine powder dissolves quickly and prevents clogging of feeding tubes.

A pill-splitter is a medication aid and organizer that is used to split various size pills and tablets into smaller sizes. It uses interchangeable pill beds to accurately split pills and tablets into equal doses.
