Bioinstrumentation or bio-medical instrumentation, is an interdisciplinary subject in the field of Biomedical Engineering that focuses on the measurement and accumulation of physiology and biology related data of humans beings using technologically modified instruments. The birth of bioinstrumentation is a result of cumulative advances in the fields of biomedical, electrical and optical engineering. The use of biomedical instruments is advancing at an exponential rate and is currently widely used in the fields of agriculture, botany and imaging systems.

History
The first use of bioinstrumentation dates back to as early as the 18th century. The first known record is from the discovery of a mummy in Thebes, Greece that had a "prosthesis in the shape of a wooden toe that was attached to the foot using a string". The invention of X-rays in the 19th century is what first sparked great interest in the research of biomedical instruments and how they can be used to diagnose and treat medical troubles. Moreover, the coming of the World Wars drove people to strive more towards medical innovation and universities started offering specialized courses related to bioinstrumentation in the field of biomedical engineering to find new and improved ways to cure conditions that restrict a person's life.

Agriculture
Bioinstruments are used immensely in the field of agriculture for monitoring and sampling the soil as well as measure plant growth. Biotechnology in agriculture requires handling compound plant genomes that is done using complex instrumentation. Devices such as tensiometers are used to measure the moisture content of the soil that helps to maintain the most favorable conditions for crop growth. Attaching an electrical transducer to it allows the crop data to be monitored at regular intervals in terms of soil moisture and water profile.

Botany
In the field of Botany, bioinstruments are widely utilized to gauge plant digestion. The PTM-48A Photosynthesis Monitor is used to register a plant's physiological qualities like carbon dioxide trade, leaf wetness, net photosynthesis and stomatal conductance.

Imaging Systems
Bioinstruments such as the ChemiDoc Touch framework is an imaging system for electrophoresis and Western blot imaging integrated with a touchscreen on a supercomputer. It utilizes application particular trays for chemiluminecscene and UV identification to offer high sensitivity and picture quality.
