Abstract
The work described was undertaken to develop a means to estimate the delivered power over the exposed body
surface of a neonate receiving phototherapy. Previous work of the group had involved the use of discrete photodiodes
distributed over a newborn manikin surface. It was considered that improved accuracy of sensing over
curved surfaces would be provided with the use of flexible solar cell elements. A group of products based on
amorphous silicon was identified as potentially suitable and a range of its properties investigated. These included
the wavelength sensitivity, the relative sensitivity of similar elements and the cosine response of elements. It was
identified that with selection of elements of matched sensitivity, specific element types were appropriate for
intended use. A total of 44 discrete solar cell elements of three separate sizes was used to cover the previously
used manikin surface and a dedicated interface circuit was designed and constructed. A handheld calibrated
spectroradiometer provided a means to relate incident irradiance values within specific wavelength bands to
corresponding optical power over the manikin surface. Initial use of the system is described together with future
potential developments in relation to clinical applications and testing standards for neonatal phototherapy
devices.
