2.4.1 Energy harvester interface
PTM 535BZ is designed to operate based on the energy supplied by a kinetic energy harvester
such as ECO 200. Refer to
[1] for a description of ECO 200.
ECO 200 provides the harvested energy to PTM 535BZ using its AC1 and AC2 output pins.
The polarity of the voltage identifies the direction of the ECO 200 action (press or release)
which is transmitted by PTM 535BZ as part of data telegrams. For press actions, the voltage
difference V(AC2) - V(AC1) is positive; for release actions this difference is negative. It is
possible to reverse this press / release encoding (so that a press is treated as a release and
vice versa) in PTM 535BZ data telegrams via the NFC interface.
PTM 535BZ provides the AC1 and AC2 supply input signals which have to be connected to
the AC1 and AC2 supply output signals of the ECO 200 harvester or another suitable power
source. Connection between PTM 535BZ and ECO 200 can either be made mechanically (di-
rect connection between the ECO 200 contacts and the PTM 535BZ contacts) or by wiring.
For a mechanical connection, PTM 535BZ provides two pairs of AC1 and AC2 contact pads on
the bottom of the PCB. Having two pairs of contacts enables the user to select the orientation
of the ECO 200 harvester according to the mechanical design needs of the application. The
AC1 and AC2 contact pads of PTM 535BZ can be mechanically connected to the AC1 and AC2
outputs of an ECO 200 kinetic harvester using a suitable fixation housing for ECO 200 and
PTM 535BZ such as the one shown on the right in
Figure 4 .
For a wired connection, PTM 535BZ provides two boundary contact signals AC1 and AC2
(shown on the right side of
Figure 3 ) which can be used for a wired connection to the AC1
and AC2 outputs of ECO 200.
Figure 4 below shows the ECO 200 harvester (on the left side) and an example for a me-
chanical integration with PTM 535BZ (on the right side). This figure also indicates the direc-
tion of movement which is a “ Press ” or “ Release ” action.
