Intrigued by the possibility of free power drove our NZ
Incorporation 12 May 2014 to investigate the [Feasibility]
of extracting energy from Personal Ambient Energy
Harvesters*. Early [Validation]prototypes delivered an average of
65uW per year (equivalent energy to a CR2032 button-cell).
However, customers' [Product Realistation] proved to be
more than 'remove the battery, insert the harvester'. A
more integrated approach was required. Transferring operations
to the UK with UK Incorporation 25 July 2021 we
filed Patent GB2619906
'Autonomous Ambient Energy Management System' 15 March
2022. Three years dedication delivered our UK IPO grant of
patent and freedom to evolve the SDC2021 Boost
Converter PMMIC and SDC2022
Boost-Buck Converter PMMIC
prototypes further. Both moved into [Design
Implementation] targeting development of the SDC2023
AEMS SoC [MP1] via our First Test Silicon [TS1]
as a "shake-down" of our Full-Custom Analogue ASIC Design Life
Cycle (c) Nov1994 (below) recently modified for use with FOSSi
PDKs under linux running the highly venerated IEEE SSCS
Open Source EDA tools thus:
* Energy available
probability fpr a battery goes from unity down to zero over each
of its cells' shelf-life whereas it can be shown that over the
usable lifetime of a solid-state electromagnetic environmental
energy harvester that probability of energy available goes
(conversely) from zero to approximately a half, over
eternity. Low-loss accumulators improve this probability to
near unity over its host product's lifetime and it is this [Realisation]
challenge we strive towards .... So, [ES1] is
coming, ... soon :-)
